Tips for Printing with digital Paper
3 Use paper designed specifically for digital printing … to maximize the image quality, toner adhesion and overall productivity of a digital piece. This is particularly the case with coated papers. What some people don't realize is that the use of offset coated sheets in a toner-based digital machine can
cause the paper to blister, crack and bubble, due to the high-heat fusing environment of a digital press.

4 Avoid metallic inks as the metallic flakes can build up on the fuser rollers. Fluorescent inks are also not recommended. Minimizing ink and water on press should help reduce the possibility of wavy paper.

5 When it comes to paper, the smoother, the better. The rougher it is, the poorer the image quality in solids and halftones. Extremely rough paper will not properly accept fused dry ink: It will rub or flake off. Using textured paper, for example, can lead to missing images. Mottle (light patches in solid color areas) occurs on rough papers, and on papers with poor or uneven formation.

6 Toner does not adhere well to heavily preprinted areas. The digital image should print directly onto the paper, avoiding an overlap of offset ink. If the job specifies an overprint of a preprinted solid area, use a halftone screen to achieve the desired color.

7 Precision sheeting is important to eliminate slitter dust (particles from sheeting) and sheet size variation, which can both affect the runnability and performance of the product. If ordering from a paper converter, select a reputable company.

8 For digital color laser printing, best results are achieved with a premium digital or business paper. For example, this sort of paper should be whiter for better color contrast, smoother with better formation (to prevent 'mottling') and have better opacity for duplex print jobs.
