Printing Guidelines | QR Code & Serialized Packaging Labels | Kang Yang

Before submitting your files for printing, Kang Yang has compiled several important points to ensure smooth production and high-quality results. We recommend reviewing these guidelines carefully prior to submission, as doing so can help prevent unnecessary errors or delays and ensure your work achieves its best possible outcome. Before submitting files, review Kang Yang’s prepress checklist: add 3 mm bleed, convert text to outlines, export CMYK, and understand color variance across materials, lamination, and reprints—so production runs smoothly and results meet brand standards.

Printing Guidelines

Before submitting your files for printing, Kang Yang has compiled several important points to ensure smooth production and high-quality results. We recommend reviewing these guidelines carefully prior to submission, as doing so can help prevent unnecessary errors or delays and ensure your work achieves its best possible outcome.


Q: What is "bleed"?

A: Bleed is a printing term and part of the prepress process. It refers to extending the design area by about 3mm beyond each edge of the final trim size. Since cutting may not always be perfectly accurate, the bleed ensures that there are no unwanted white edges after trimming.

Q: What is converting text to outlines?

A: Due to font licensing issues, to avoid printing errors caused by different glyphs, please convert text to outlines (curves). After converting text to outlines, the original font becomes an object, allowing the same text design to be displayed on different computers.

Q: Color mode of image files: CMYK and RGB

A: The color mode of the web is RGB, and the color mode of printing is CMYK. Therefore, color differences will inevitably occur during printing. For good printing quality, please provide files in CMYK output mode to minimize color differences.

Q: Can the same color be displayed on different materials such as screens and photos?

A: The same color cannot be displayed the same on different materials such as screens and photos! The color effects displayed on computer screens, inkjet drafts, photos, and large-scale printed paper will all be different, so they cannot be used as a reference for printing colors. For illustrations, please use actual printed products as a reference. Web color display is for reference only.

Q: Will the color change after lamination?

A: After lamination, stickers, labels, and printed products are already processed, so the color after lamination cannot be predicted during printing, and even sample printing cannot achieve zero color difference.

Q: Will the color be the same in different print runs of the same file?

A: In different print runs of the same file, there may be slight color differences due to density, temperature, and other issues. A color difference of about 3% from the sample is considered normal.

Printing Guidelines | Prepress Guidelines for Label Printing: 3 mm Bleed, CMYK & Outlines

Prepare print-ready files that avoid delays and color surprises. Add a 3 mm bleed on every edge to prevent white borders after trimming, keep critical text and logos inside the safe zone, and export a single, flattened PDF with linked images embedded at 300 dpi.

For reliable output across devices, convert all text to outlines to eliminate font licensing or glyph issues. Set artwork to CMYK (not RGB) and use consistent color builds or Pantone references when possible. Remember that screens, inkjet proofs, photos, and press sheets will display color differently—web previews are for reference only.

Expect minor variation between runs due to density and temperature; a ~3% color difference is normal. Lamination and special finishes can shift perceived color, so approve on-press or request a production-method sample for critical jobs. Following this checklist ensures smooth production and high-quality results.
