«NOTICE»
1. Be careful that the blanket recovery solution and other chemicals
do not adhere on the blanket cylinder surface. If they adhere on the
blanket cylinder surface, wipe them off with a cotton rag containing
water and cleaning solution immediately. Make sure that the cylinder
is completely dry, and then apply rust preventive oil over the entire
surface of the blanket cylinder.
2.
When using the gauge film with the blanket cylinder, clean the
cylinder surface well and dry it completely before mounting the gauge
film.
Also, mount the gauge film so that it contacts the entire surface of
the cylinder. If there is any clearance between the film and cylinder,
water, etching solution, and the other chemicals will enter into the
clearance and rust will form.
