Explore the coloring science behind paper making and the machinery that shapes it.
This volume surveys how pigments and dyes are used to color paper, including how they behave with paper stock, light exposure, and processing methods. It explains the factors that affect color fastness, shade control, and uniformity across different grades of paper. The text also covers the sources of coal tar dyes and the manufacture of intermediates, giving practical context for mill operations and quality control.
- Learn about key pigment families such as ochers, siennas, umbers, iron oxides, chrome yellows, Prussian blues, ultramarines, sap brown, and lamp black.
- Understand how dyes and pigments differ in form, application, and impact on strength, weight, and color stability.
- Discover the origin of coal tar dyes and the steps to produce intermediates used in coloring.
- See how processing factors like temperature, dilution, and mixing timing influence shading and consistency in paper.
Ideal for readers working in pulp and paper mills, color control, and paper quality assurance, as well as technical students seeking a practical reference.
