BS ISO 12636:2018,Graphic technology – Blankets for offset printing.BS ISO 12636:2018 pdf  free download.The size is 2.07M.
The blanket is an essential part of every offset printing press. Its properties exert a profound influence on the mechanical conditions within the press and the visual characteristics of the prints produced. It is therefore useful to provide test methods, unified data, and tolerances for some essential properties of the blankets. This permits the suppliers to state properties of blanket types in a standardized and Universally understood manner. It also helps the printer to select the appropriate blanket type for a particular press type or press condition. A further benefit is that the design of printing presses can be based on blanket data resulting from unified test methods.
BS ISO 12636:2018 defines vocabulary and specifies test methods, characteristics, ordering and labelling information for blankets for offset printing. This document does not apply to un-tensioned or unclamped blankets for offset printing, nor offset printing sleeves used on gapless presses.
4 Requirements
4.1 Information
The compatibility of the blankets to either conventional, dual use or ultraviolet (UV) inks shall be documented.
The overall hardness and the microhardness are not specified in this document. They are the choice of the manufacturer. If the manufacturer provides such information, the test method shall also be documented and mentioned with the results.
