7. Color Mode
All files must be created in CMYK color mode.8. Minimum Line Thickness
Lines thinner than 0.076 mm cannot be printed. Use a minimum of 0.076 mm.9. Minimum Color Value
Do not set color values lower than 8%, or the colors may not appear in print.10. Color Guidelines
- Screen colors or desktop printer outputs cannot be used as the standard for final print colors.
Do not use spot colors for general filling. Always follow CMYK percentage values.
Any color variation caused by incorrect color mode or spot-color usage is not eligible for reprint or refund. - Slight color variations may occur in different print runs of the same file.
Colors such as brown, dark green, and dark purple are especially prone to shifting—this is normal. - For black text, do not use rich black (C100 M100 Y100 K100).
Avoid total ink coverage exceeding 250%, especially in large areas, as it may cause set-off (ink transfer) during printing.
