The difference between color printing album and black and white album printing lies in the change of color. When dealing with color album printing, we should pay special attention to the factors that affect color. Shanghua Color Printing introduces several points:
1. Whiteness of paper
If the whiteness of the paper we use for color printing is otal reflection, and we should pay attention to the size and color of the paper when printing the same series of products.
2. Influence of environmental color
Environment has a great influence on color discrimination, and it will make us have the illusion of color. At the same time, the solid color blocks of proofing and printing samples can be juxtaposed together, and the interference of environmental colors should be eliminated to avoid color deviation caused by vision.
3. The Relationship between the Absorption of Paper and the Imprinting Ink Layer
Each kind of paper has different ink absorption. We should choose different ink systems according to different papers. When using paper with poor quality, loose structure and rough surface, in order to avoid ink color error that may occur during sample signing, the printing sample can be placed for a certain time, and the color use degree can be determined after drying.
