Definitions
- the invention relates to a method for printing on paper by gravure printing.
- the printing form has depressions that receive the printing ink that is transferred to the paper during printing.
- the paper to be printed must have as smooth a surface as possible; furthermore, the paper should have a high degree of flexibility so that it fits well into the indentations when picking up color.
- a measure of the quality of the printability in gravure printing is e.g. the number of missing points, the so-called "missing dots”.
- the papers to be printed are generally coated with a paper coating slip.
- Binders with a butadiene content of 0 to 100% by weight were known from EP-A-408 099. Binders with a butadiene content of approx. 36% by weight were used in paper coating slips in accordance with the examples.
- the object of the present invention was a method for printing on papers which particularly fulfills the requirements in gravure printing. Accordingly, a process for printing papers by gravure printing has been found, characterized in that the papers are coated with a paper coating slip which contains a binder with a butadiene content of at least 65% by weight, based on the binder.
- the paper coating slips contain a binder as an essential component.
