色 & Prepress Standards
Monitors generate visuals in RGB additive color space, whereas Heidelberg presses print in CMYK subtractive inks. Understanding this difference prevents unexpected color shifts.
RGB Screen vs. CMYK Inks
Some electric neon RGB colors lie outside the CMYK gamut. Our prepress team uses ISO 12647 color profiles to maintain maximum vibrance.
Pantone (PMS) Spot Inks
For exact brand colors, metallic golds, and ultra-bright pastels, we mix custom 5th and 6th Pantone spot ink formulations.
Sample Orders & Refund Policy
We provide flexible sample options so you can verify paper weights, binding construction, and print finishes before mass production:
Pre-Production Sample Reimbursement Policy
When you order a custom physical proof (covering your specific cover materials, interior paper, and foil dies), the initial sample fee is 100% credited directly against your final bulk production invoice when your order reaches standard MOQ.
