Frequently asked questions
When should I convert to CMYK?
CMYK is required for professional printing. Convert your PDF to CMYK before sending it to a print shop to ensure accurate color reproduction.
What is the total ink limit?
The total ink limit controls the maximum combined percentage of CMYK inks. Standard offset printing typically uses 300-340%. Newspaper printing often requires lower limits around 240%.
Will colors look different after conversion?
Some color shift is normal when converting between color spaces (especially RGB to CMYK) because each space represents different color gamuts.
Can I convert a Grayscale PDF to color?
Converting Grayscale to RGB or CMYK will not add color — it changes the color space metadata. The visual appearance remains grayscale.
