Product Editor Guide

Design on Stanley/Stella Garments. See the Result Before You Order.

The Caspar Product Editor lets you place your artwork on premium Stanley/Stella garments, preview every detail in real time and save your design for later. It works for DTG printing and embroidery, and you can combine both on one product.

Before You Start

Get Your File Ready First

Five minutes of preparation saves you a re-sending design later. The editor checks your resolution automatically, but it cannot fix a file that was prepared at the wrong size.

Full File Preparation Guide →

  • ✓ File type: PNG or JPEG
  • ✓ Colour space and profile: RGB, Adobe RGB (1998)
  • ✓ Resolution: 150 DPI at the size you want printed
  • ✓ Maximum file size: 40 MB
  • ✓ Clean file: remove anything you do not want printed (transparent backgrounds, stray brush strokes) and crop empty space on all four sides
  • ✓ Actual scale: a 20 × 20 cm file at 150 DPI prints exactly 20 × 20 cm
Choose Your Decoration

DTG Printing, Embroidery or Both

You choose a decoration for each print position. You can mix both techniques on one product, for example a printed design on the front and an embroidered logo on the chest.

After you upload: the carousel toolbar

Once a file is on the product, a second toolbar appears below the editor. Use it to adjust:

  • 1 File repeat, to tile the image

  • 3 Alignment of the image within the design area

The lock icon between Width and Height: when locked, your file scales proportionally and keeps its original aspect ratio. When unlocked, you can change width and height independently for custom scaling.

Watch for the Resolution Warning

If your file has a lower DPI than recommended at the size you chose, a clear warning appears above the editor. It appears again in a pop-up when you try to add the product to your cart, so you never print a blurry design by accident.

How to fix it: make the design smaller in the editor, or upload a higher-resolution file prepared at 150 DPI at the actual print size.

Avoid These

Five Common Mistakes (and Quick Fixes)

🔍

Ignoring the resolution warning

A low-DPI file prints soft. Upload a 150 DPI file prepared at the real print size.

👻

Thinking a design vanished

Switching position hides the other file, it does not delete it. Switch back or use the preview.

🖼️

Empty space around the design

Extra margin shrinks your artwork on the garment. Crop all four sides before uploading.

↔️

Stretched artwork

Unlocking the lock icon lets width and height change separately. Keep it locked to preserve proportions.

💾

Forgetting to save

Click Create Product so the design is stored in your account and ready to reuse.

🧪

Skipping a sample

Screen and print colours never match 1:1. Order one sample before you launch.

FAQ

Editor Questions

The questions we hear most from new users.

Design & Create FAQ →

Can I combine DTG printing and embroidery on one product?

Yes. Both techniques can be used on a single product in the same editor, for example a printed design on the front and an embroidered logo on the chest.

I switched print positions and my design disappeared. Is it gone?

No. Files stay on the position you uploaded them to. Switch back to that position, or click the eye icon to preview all positions together.

Why do I see a low-resolution warning?

Your file has a lower DPI than recommended at the size you placed it. Upload a higher-resolution file, or reduce the design size in the editor. We require 150 DPI at the actual print size.

Can I reuse a design on a different product?

Yes. Once saved, your design lives in your account. Use Browse Designs to place it on another product without uploading it again.

Can I download the mockup?

Yes. Click the download icon in the toolbar to save the mockup to your device at any time.
