Key takeaways
- Start from your press: final size, 3 mm of bleed, at least 300 DPI at final size and CMYK are the safe values in Printcart's print-ready file tutorial.
- Set a design area with bleed on every side of every product, so the customer's design and the PDF match the press sheet.
- Decide per product whether customers design online, upload their own file or both, and set the upload rules: file types, number of files, size limit and minimum DPI.
- Place a test order, on a phone too, and open the print-ready PDF from the order before you take real orders.
- Printcart's Free plan includes CMYK print-ready export; Premium is $49 a month or $299 a year ($300 on Wix), and Printcart can also set the app up for you.

What does print-ready PDF output mean for an online product designer?
Print-ready PDF output means that every order placed through the designer arrives with a file your press can print without anyone rebuilding the design: the right final size, bleed around the edges, enough resolution and the colour mode the press expects. An online product designer that only saves a preview image leaves that work to your prepress team on every order.
The customer never sees the PDF. They see an online product designer on the product page, where they add text, photos or a logo, pick a template and preview the result before checkout. Behind it, the designer has to turn that design into a production file, and that is the part this guide sets up. For what the designer itself should offer, see what an online product designer is and the product designer feature checklist.

Before you set up the designer, you need three things: a store where customers order, the list of products customers will personalise, and the print specs of each product from your press or print partner. The specs matter most, because the design area, the bleed and the upload rules you set later all come from them, and a wrong value repeats on every order.
A store comes first because the designer is added to it. Printcart has a WordPress/WooCommerce plugin, a Shopify app and a Wix app, listed on its apps page. The WooCommerce plugin needs WordPress 5.0 or higher, PHP 7.4 or higher and WooCommerce. A print shop without a store yet can compare ecommerce platforms for print businesses first.
For the specs, Printcart's tutorial on preparing print-ready files gives safe values: at least 300 DPI at final size, 3 mm of bleed, print colour settings, which means CMYK for most presses, and outlined or embedded fonts. It names resolution, bleed, safe margins, colour and fonts as the five issues behind most reprints. If your press asks for other values, use theirs.
| Product | What to ask your press for | Where it goes in the designer |
|---|---|---|
| Business cards, flyers | Final size, bleed, safe margin, paper and finish | Design area with bleed; printing options for paper, finish and quantity |
| T-shirts and apparel | Print area per side and size, print method | One side per print area (front, back, sleeve); colour and size options |
| Stickers and labels | Final size or shape, bleed, cut line | Design area per shape; upload rules for customer artwork |
| Mugs and drinkware | Wrap area and safe zone | Design area matching the wrap |
How do you set up an online product designer with print-ready PDF output?
You set it up in seven steps, from the print specs to a test order whose PDF you open yourself. The steps follow the set-up described on Printcart's WooCommerce plugin page and Shopify app page; the WooCommerce page says you can go from a fresh install to your first print-ready order in a few steps.
Step by step
Step 1: Write down the print specs of each product
Ask your press or print partner for each product's final size, bleed, resolution and colour mode. Printcart's print-ready file tutorial gives at least 300 DPI at final size, 3 mm of bleed and CMYK for most presses as safe values.
Step 2: Install the designer app on your store
On WooCommerce, add Printcart Store from the WordPress.org plugin directory and activate it; on Shopify, add the Printcart Product Personalizer from the Shopify App Store; Wix has its own Printcart app.
Step 3: Connect the store to a Printcart account
The set-up wizard starts with Connect, which links your site to a Printcart account used for licence verification, cloud processing and order tracking.
Step 4: Import products and set the design areas
Import your products or the sample products, add the sides of each product and set the design area, or apply a side template; size each area to the print specs, bleed included.
Step 5: Choose design, upload or both
Turn on the designer, customer upload or both for each product. For uploads, set the allowed file types, the number of files, the size limit and the minimum DPI, then add printing options and prices.
Step 6: Place a test order and open the PDF
Open a product page as a buyer, on a phone too, design or upload a file and order. Open the order and its print-ready PDF, and check size, bleed, resolution and colour against your specs.
Step 7: Send the files to production
Download the print files from the order or the Printcart Dashboard, or pass orders to automated fulfilment with the Printcart Cloud Print API.
The first real order should be one you place yourself. Printcart's WooCommerce page tells you to test the shop as a buyer, including on a phone, and then to open the order under WooCommerce orders, review the design and open its print-ready PDF from the order screen. On Shopify, orders and uploaded files are reviewed in the Printcart Dashboard, where you download the print files for production.
How do you set design areas, bleed and resolution for each product?
Set one design area for each printable side of a product, sized to the press specs with the bleed included, so the customer designs on the same shape your press will print. On Shopify, Printcart adds sides to each product and sets the design area, or applies a side template that defines it for you, and shoppers personalise inside the safe print areas you define.
Bleed is the strip of design that runs past the cut line, so a small shift in cutting leaves no white edge. If the design area stops at the cut line, the PDF has no bleed and a card or flyer can come back with a white edge. Keep text and logos inside the safe margin, away from the cut.
Resolution is the setting customers break most often, because they upload a photo from a phone or a logo from a website. Printcart's upload settings let you choose the allowed file types, the number of uploads, the size limits and the minimum DPI, and its AI tools for print quality include preflight checks, background removal and image upscaling, per the WooCommerce plugin page. Printcart's artwork upload and AI tools pages show how a full store uses them.
How do you check the file before it goes to press?
Check the first files by hand: open the PDF from the test order and compare it with the press specs for final size, bleed, resolution, colour mode and fonts. Do the same for one designed order and one uploaded file, because the two paths produce files in different ways, and repeat the check whenever you add a product type or change a design area.
Printcart says every order produces high-resolution print-ready files in PDF, SVG, PNG and JPG CMYK, and the order keeps the options the buyer chose, so production knows the paper, size and quantity. In a Printcart full store, print-ready CMYK files are generated and stored for every order, and the canvas store makes a print-ready PDF per order line with wrap and bleed.
For orders where the customer must approve the final layout, add a proof step before production. Our proof approval workflow explains when a proof is worth the delay, and the print-ready file policy lists what to check, fix or reject when a file arrives.
What does the designer cost, and can someone set it up for you?
Printcart's Free plan includes an online designer on the storefront, CMYK print-ready export and community support, with limited products and storage. Premium is $49 a month billed monthly or $299 a year billed yearly ($300 a year on Wix), with up to 100 products with the public designer, 500 order-upload file downloads per month and priority support, per its store-plans page, as of 26 October 2026.
If you would rather not do the set-up yourself, Printcart's set-up services for WooCommerce, Shopify and Wix connect the store, enable products, set printing options, place the storefront button and verify one test order, delivered remotely. A print shop that wants the whole store built can start from a full-store package: the Store package is USD 799 a year with the Printcart Premium licence and 10 of your products set up, and the business card printing store shows the result with a live demo.
Other designers also produce print files, with different formats, plans and fees. Our comparisons hold them to the same criteria: WooCommerce product designer plugins, Shopify product customizer apps, customizer apps for UK print-on-demand sellers and web-to-print software for small print shops.
Frequently asked questions
How do I offer an online product designer with print-ready PDF output in my print shop?
Install a product designer that writes a print-ready file for every order, set each product's design area to your press specs with bleed, choose design or upload per product, then place a test order and open the PDF. With Printcart on WooCommerce, Shopify or Wix, every order produces print-ready PDF, SVG, PNG and JPG CMYK files.[1][2]
What makes a PDF print-ready?
A print-ready file has the right size, at least 300 DPI at final size, 3 mm of bleed, print colour settings, which means CMYK for most presses, and outlined or embedded fonts, according to Printcart's tutorial on preparing print-ready files. Your press may ask for other values, so take its specs first.[5]
Does Printcart's Free plan include print-ready output?
Yes. Printcart's Free plan lists an online designer on the storefront, CMYK print-ready export and community support, with limited products and storage. Premium is $49 a month billed monthly or $299 a year billed yearly ($300 a year on Wix), with up to 100 products with the public designer and 500 order-upload file downloads per month, as of 26 October 2026.[4]
Can customers upload their own artwork instead of using the designer?
Yes. In Printcart you turn on the designer, customer upload or both for each product. For uploads you choose the allowed file types, the number of uploads, the size limits and the minimum DPI, so a file that is too small is caught before the order reaches production.[1]
Can Printcart set up the designer for me?
Yes. Printcart's set-up services for WooCommerce and Shopify connect the store, enable products, set printing options, place the storefront button and verify one test order, delivered remotely. A business that wants the whole store can start from a full-store package at USD 799 a year.[7][8]
