The following is a brief reference to the workability and printability of actual newspaper letterpress printing.
1. Workability
Web breaks, in many cases, are largely related to the horizontal tear strength (CD) and the vertical tensile strength (MD). Therefore, the break rate can be anticipated by assessing the tear and tensile strengths.
The rolling strength applied to webs is very significant in determining the amount of creases becauses the tension applied to webs changes on the press.
2. Printability
It is important to give due consideration to the surface property and sheet-formation of webs so that blurs on solid prints can be minimized.
