The Screen Printing Process | Every Step It Takes To Screen Print

The screen printing process is a mystery to many new screen printers. While the overall process is simple enough, there are lots of details to learn.

Before you dive in and spend thousands on new screen printing equipment, take some time to learn about the process. Screen printing is process oriented – meaning that if something goes wrong, you may have to start over at the first step.

If you're looking to make some quick cash printing shirts, understanding that there's a process you must adhere to will help you hustle harder – with more consistent results for your customers.

The basic screen printing process has three phases:

• Pre-press: everything before t-shirt is printed, from sales to artwork to preparation for printing. The majority of time is spent in this phase.
• On-press: printing the apparel or merchandise. This is a small but crucial part of the overall process.
• Post-press: shipping or delivering the product, following up, getting reviews. This is where businesses struggle or thrive.

The most important part of the screen printing process is preparation.

You will hear this time and time again from industry professionals: great prints start with a great pre-press process!

Pre-press preparation and organization is the key to successful growth in screen printing.

The typical pre-press process doesn’t begin when a screen printer arrives at their shop and starts putting ink onto a screen.

We’re going to spend a lot of time on the details and edge-cases during the pre-press process. We can’t overemphasize how important this entire section is to your success. The smoother, faster, and easier your pre-press process, the better your business can become.

Step 1: Sales

So screen printing doesn't begin with ink or shirts. No, the screen printing process begins with sales.

We’ve written extensively about screen printing sales. Each and every shop has their own methods for getting sales, and each salesperson typically has their own unique style for attaining sales.

But what does it mean to make sales part of your screen printing process?

You must sell profitable orders that your shop can print on time and up to the customer’s expectations. Nailing your screen printing prices isn't as important as you think. It's more important to provide a lot of value to your customers. More on that in a moment.

If you sell a screen printing job you can’t actually print, what should you do?

Maybe you can find a contract printer to take it on – but if you’re new or don’t have contract printer connections, you need to take your shop’s ability into account while you are selling. In other words, don't sell jobs you can't actually print unless you know a good printer that will help you out!

As a rule of thumb, you should sell screen printing orders that are:

• Larger than 24 pieces (so it’s worth your time to print!)
• Easier to print, with fewer colors (so your quality is high and costs are low)
• Easy to meet deadlines for (so you aren’t waiting on shirts that are backordered)

Most print shops choose two to five niches that they capitalize on, and that's how they provide real value to their customers.

For example, some prints shops focus exclusively on printing highly detailed images of cars for car enthusiasts and auto shows. They provide value by knowing the right cars to feature, the right people to market to, and the right way to print these demanding images.

Some only print high-visibility merchandise for government agencies. They provide value by understanding the inks that work best with high-vis, and they even understand the legal requirements that their garments might have to meet. They know the local Department of Transportation real well!

And still other screen printers are dedicated entirely to band merchandise for music tours. They know which bands to target, what products to offer, and what kinds of things actually work when you're selling merchandise.

The point is that you should nail your niche to get more sales and make the process easier. Industry expert Mark Coudray told us at PrintHustlers Conf: "The riches are in the niches!"

Note: we've written extensively about how to get more sales for screen printing.

Step 2: Quote and artwork approval

One of the trickiest parts of the screen printing process is the Quote and artwork approval process. 

Did you ever think about this? Your customer needs to approve – in detail! – every part of the project you're working with them on. After all, it's a totally custom project!

More importantly, we’ve discovered that print shops typically have thousands of dollars in outstanding orders that are stuck. They're just quotes that never got approved!

You’ve sold the job, agreed on the numbers, but still need to get the green light from your customer that every single detail is correct. So nail that process as a screen printer and you'll make more money, faster.

Without complete approval, you’re gambling with your business: what if the customer wanted a change, something was misspelled, or they want more shirts at the last minute? 

Your approvals process should give you time to plan the job appropriately! You need to account for approvals in your turnaround time: if a customer wants something in 5 days, is that actually enough time to print the order...and go through approvals for quotes, art, and more?

We recommend that you implement some kind of well-documented system to help you track and organize your quote and artwork approvals. \

Note: Printavo’s screen printing management software has a powerful automated system for staying on top of your Quotes and Artwork approvals.

Step 3: Choosing the right garments and inks

Once your quote and artwork have been accepted by the customer, you have to figure out the puzzle: how do you actually make this design and print come to life? 

There are virtually unlimited combinations of garments, inks, and printing processes in screen printing.

Hopefully you're not planning to use pink ink on a black shirt without using an underbase – you do know what an underbase is, right?

Are you printing plastisol on cotton, keeping it super easy or simple? Or are you going to use water based inks alongside a discharge underbase to make the print feel like the t-shirt? Maybe you're trying to figure out how to get a softer screen print?

You must understand screen printing ink and how it interacts with fabrics to nail this step.

Or, keep it simple and just offer limited options to your customers. Good, better, best is a simple and classic way to organize the merchandise quality you offer. 

Weird fact: many people consider the most affordable mass-produced t-shirts (thick, heavy cotton tees) to be the "highest quality" shirts.

Step 4: Ordering wholesale t-shirts and garments

The odds are good you don’t have the right garments on hand, unless you keep a lot of inventory on hand. Most screen printers in the US don't keep large amounts of inventory (though the shop pictured above is an obvious exception – they print thousands of shirts a day).

So, if you're like most screen printers, you’ll order apparel through a wholesaler.

The major garment suppliers in the US are:

• SanMar
• Alphabroder
• S&S Activewear
• TSC Apparel

Each garment wholesaler specializes in different areas: SanMar offers exclusive lines like Nike, Carhartt and more, alphabroder has a truly giant inventory, S&S Activewear is known for speed and consistently, and TSC Apparel provides some of the best athletic apparel. 

"SanMar was founded by my father, a decorator. SanMar started because he got a big screen printing order for the Seattle Supersonics and had to order a bunch of t-shirts for it." - Jeremy Lott from SanMar

It’s great to have a working relationship with these wholesalers. They're supportive and know how important it is to maintain a close connection to screen printers. 

You can learn how to order t-shirts from wholesale vendors quickly: they're eager for business!

Note: each wholesaler listed here is integrated directly into Printavo, making quoting and sales a super seamless process. Just punch in the item you’re looking for by name and you'll have quick access to pricing and more.

Be sure to proactively plan your wholesale shipments: it may take 3-5 business days just to receive certain merchandise.

Step 5: Intake and internal communication about the order

You’ve sold the order, got the goods, and are so close to printing that you can taste it.

But don’t rush through this next step: it’s crucial!

Order intake is part of your sales process, yes – it’s the details you take from the customer to get specific information about the customer and what they need.

But this step is also the process you use to receive garments and "stage" orders when they arrive at your shop.

Most shops use a combination of wheeled carts or bins to control the flow of t-shirts. It’s best to have a clear system in place for receiving that ensures your team isn’t losing garments, misplacing items, or otherwise disrupting the smooth flow of an order through your shop.

This same process is part-and-parcel of the internal communication process in your shop. We think the way Printavo handles this process is incredibly smooth, so we want to share it. 

Once a Quote has been approved, the order is moved to a custom job status in Printavo called ORDER INTAKE - GOODS INCOMING.

Everyone in the shop can always see what status jobs are in, so anyone that visits that job knows what’s happening with it. Changing the status can send a notification via text or email as well.

Usually, the intake department will then handle the order.

Once they’ve got the goods counted in and ready to print, they’ll change the job to a status like GOODS READY - PREPARE SCREENS. Then, the next department – the screen room – takes control of the job.

Step 6: Making screens for screen printing

Once everyone in your shop is on the same page about the order, and your customer has confirmed the Quote and approved the artwork...it’s time to make (or more accurately: image) your screens.

If there’s one technical skill to master as a screen printer, it’s everything that goes into making great screens.

From emulsion to exposure, you want to have the best possible understanding of the basics of making screens if you want to be a great screen printer.

Here’s the basic process for making screens for screen printing:

1. Ensure your screens are clean and free of emulsion, inks, debris, and tears. Good, clean screens are a must. Use a quality screen cleaner to clean your screens each and every time you print. Ideally, you use a tension measuring device to ensure your screens are the correct tension each time they are reclaimed.
2. Coat your screens with emulsion. Apply a thin, even layer of emulsion on both sides of the screen with a scoop coater. 
   1. What is "emulsion" for screen printing? It's a light-sensitive chemical designed to harden when exposed to light.
3. Let the screen dry. Emulsion takes some time to dry. We suggest using a dust-free area, such as a cabinet or container – and keeping it away from any dirty areas in your shop, including your washout booth.
4. Image the screen. Typically, screen printers use transparent films printed by an Epson inkjet printer to image their screens. You’ll line up your transparencies, then expose your screens to a powerful light (your exposure unit).
   1. What does "imaging" mean? This will harden all of the emulsion except the emulsion hidden from light by the ink on the transparent film. Think of this like creating a “stencil” for your ink to pass through.
5. Wash the screen out. You use water to rinse out emulsion that wasn’t hardened by the exposure unit. Typically, shops also check to ensure that they’ve achieved a high-quality stencil image at this time – all edges, details, and important features are preserved. The screen is then dried or wiped down again at this point.
6. Set the screens up (register the screens). Screens for one-color jobs are simply aligned with the platen on the screen printing press. Screens for multiple color jobs must be registered correctly  – meaning that all of the screens align precisely with each other. How long does it take to register screens? Registration can be a time-consuming and challenging process, taking anywhere from 10 minutes to an hour or more for a complicated screen printing job. Most shops stage their screens for each job while a press operator is responsible for setting up and breaking down their own screens.
7. Print. Finally! Screens can be used and reused as long as the emulsion doesn’t break down or the screen doesn’t fail – some shops even keep screens for their most common designs and logos on hand.
8. Clean and reclaim the screens. Screens are used and re-used, so a used screen goes through a simple process to “reclaim” it. Ink is removed, the screen is soaked in a chemical to help remove the hardened emulsion, then a pressure washer is used to remove all emulsion from the screen. Many shops use additional chemicals (such as degreasers and dehazers) to keep their screens pristine.

The screen process is, if you didn’t notice, a loop. Screens travel through this process over and over until they’re worn out, lose tension, or break.

But, no matter how you image your screens (or the exact process your shop uses to make screens), your screens are the single most important operational detail relating to quality. Great print shops know how to make great screens, full stop.

Step 7: Printing on press...where the action happens

While it’s exciting to print t-shirts, your actual on-press time is a sliver of your business.  Preparation is everything in screen printing.

It’s not unusual for the administration (read: the order intake, quote approval, art approvals and revisions) and preparation (the pre-press process) for a screen printing order to take longer than the actual printing. Think about it: a 250 piece order might take 5 hours of time to agree on – but only an hour or two to actually print.

Screen printing is about much more than dragging a squeegee across a screen: it’s a process and the actual printing is just a small part of that process. Get one piece of the screen printing process wrong and you’ll likely have to start over from the first step.

There aren’t many businesses that have such a process-intensive product – so treat the screen printing process with respect!

Most screen printers follow a process like this while printing:

• Press operator stages the t-shirts and supplies. They may or may not receive the t-shirts they will print. Typically, they’ll use a printed Work Order or an on-press tablet to confirm details of the job. Inks, squeegees, spray tack, t-squares, and other tools are retrieved as needed. This may or may not fall under your pre-press process – in a large, automated shop, the press operator is typically handed everything they need to print the job and never leaves the press. In a smaller shop, the press operator may do many jobs!
• The t-shirts are printed - the press operator loads, prints, and unloads the shirts. Load t-shirts onto the platen, ensuring they’re centered every time. Use spray tack to keep your platen sticky so the shirt doesn’t move while you print it. You (hopefully) pull your squeegee across the ink, versus pushing it. Unload t-shirts and send them through your curing dryer immediately.
• The ink on the t-shirts is cured. Depending on the type of ink you use, you will have to cure your ink. Water based inks take about 3x longer to cure than traditional plastisol inks! Most plastisol inks need to reach an internal temperature for a set amount of time – be sure to carefully read the details of any ink you use. If you don’t cure your inks correctly, the prints will wash out – and your customers will be upset.

Step 8: Quality assurance, shipping, and beyond!

We’ve meticulously prepared our order, done the hard work of printing it, and now we must do three crucial things that every screen printing business should do:

1. Assure quality through a QA (quality assurance) process. Most larger shops have a person dedicated to checking each and every t-shirt after it is printed and cured. This role is often called the “catcher.” This person is the first line of defense again spoilage and misprints – so they’re very important!
2. Package and ship. Whether you bag-and-tag, ship straight through polymailers, let customers pick up, or deliver directly – you must ensure every product gets to every customer accurately. Always include a postcard, sticker, or other Thank You goodie with every product you sell – this increases retention and makes it more likely the customer will mention you positively on social media.
3. Follow up and get a review. Bad reviews on Google, Yelp, and social media will kill your business! You should seriously consider building a way to get reviews. Always ask for reviews – whether it’s in a follow-up email, phone call, postcard, or social media post. You can STOP bad reviews by asking people to contact you if there’s a problem with their order.

Conclusion: Process first (if you want to succeed at screen printing)

The biggest and most important insight we can leave you with is this: screen printing is a process.

While you are making a product, the real product of any screen print shop is actually its process. Each job is custom, unique, and totally different – so what stays the same is the processes underlying each job. 

Good preparation is essential to good screen printing.

There is not a successful screen print shop that ignores the process and leaves it to chance in the entire world.

Screen printing and process-first thinking go together like bread and butter.

The three-phase process you should focus on involves pre-press activities (where you should and will spend the majority of your business’ time), on-press printing (often just a fraction of the revenue-generating time in your business), and finally post-production follow-ups (to build and maintain customer relationships, get reviews, and keep your business in good standing).
