Can you rely on the screen for color accuracy? No. Screen backlighting tends to make colors appear brighter and more vivid, and there are often inconsistencies between mobile and computer displays; screen views are merely for reference—the physical sample is the true basis for judgment. For remote color approval, rely on a combination of photos and the physical sample itself.
How do you check for color deviation during acceptance? Compare colors under natural light, avoiding yellow lighting or mobile screens; agree on a specific color difference value (ΔE) as the acceptance standard; and for bulk production, compare samples based on a set inspection ratio. Including color standards in the contract provides a clear basis for acceptance.
How can color deviation be minimized? Use printed color charts for matching; Pantone color codes are the universal standard—providing a code is far more reliable than saying “I want this shade of red.” Color consistency is best maintained by using the same factory, paper stock, and production batch; switching factories or paper essentially requires starting the color-matching process over.
Why does the packaging color differ from the design proof? Because screens and paper are fundamentally different: screens emit light, whereas paper surfaces reflect it. Design proofs often use RGB colors that fall outside the CMYK color gamut used in printing, inevitably leading to discrepancies. Always use the physical proof as the color standard, not the screen.
Will the colors of the proof and the bulk production differ? Slight variations are possible and are a normal occurrence in the printing industry. To manage this, keep a reference sample: the signed proof serves as the benchmark against which bulk goods are accepted. Re-confirmation is necessary whenever production batches or paper stock batches change.
How do you match dark colors, gold, and silver? Dark colors are highly sensitive to deviation; even minute changes in ink volume are visible to the naked eye. Metallic colors (gold, silver, holographic) are heavily influenced by the paper stock; printing light colors on gold or silver cardstock requires a white base layer. Verifying these colors through physical proofs is particularly important.
