Research on the Effects of the Basic Properties of Offset Paper and Art Paper on Printing Dot Reproduction
The properties of offset paper and art paper including smoothness, gloss and absorbability, dot percentage and the tri-stimulus values of every dot areas and solid areas of the printed paper samples were measured. Dot gain curve and chromatic diagram were drawn after dot gain values and chromatic coordinates (x, y) were calculated. The results showed that smaller dot gain value and greater color gamut occur on the art paper due to its higher smoothness, gloss and lower absorbability when the printing conditions were the same, so the printing dot reproduction quality on the surface of art paper is better. However because offset paper has lower smoothness and gloss, higher absorbability compared with art paper, therefore the dot reproduction quality on offset paper is not as good as art paper.
