20 answers in this topic. Select a question for its dedicated reference page.
01What is RGB versus CMYK?
RGB uses light for screens; CMYK uses inks for print and has a smaller color gamut.
02Should I convert RGB to CMYK?
Follow the printer’s workflow. Some prefer RGB with an embedded profile; others request CMYK.
03Why do print and screen colors differ?
Screens emit light while paper reflects it; profiles, ink, paper and viewing light all matter.
04What is a color profile?
A description of how a device or color space represents color, used for predictable conversion.
05What is soft proofing?
A calibrated-display simulation of a target print condition.
06What is rich black?
Black combined with other inks for large dark areas. Avoid it for small text unless specified.
07What CMYK is black text?
0C 0M 0Y 100K is common for small black text; follow print provider requirements.
08What is a spot color?
A separate named or premixed ink, often used for brand matching or special effects.
09Can every RGB color print?
No. Bright screen colors can fall outside the printable CMYK gamut.
10Why does black look gray?
Ink density, paper, profiles or a screen-style black may be responsible; proof critical work.
11What is total ink coverage?
The combined CMYK percentage in an area, limited to avoid production issues.
12Should I use Pantone?
Use a spot-color system when specific brand matching or a special ink is required and offered.
13What is color banding?
Visible stepping in gradients, caused by limited tonal data, settings or device output.
14Why does a gradient change in print?
Gamut conversion, screening, paper and tonal range can alter it; proof critical gradients.
15How do I prepare logo color?
Keep the logo vector and use approved CMYK or spot values for the actual process.
16What lighting should judge print?
Consistent neutral light close to the provider’s proofing condition is best.
17Does matte paper affect color?
Yes. It often appears less saturated than gloss but reduces glare.
18What is registration?
Alignment of separate color plates or passes during printing.
19Why avoid four-color black text?
Plate misalignment can create colored edges and soften small text.
20What is a press proof?
A physical preview made on or close to the intended output process.
