The use of a compressible material as underpacking is fundamental with all the new generation coating plates which, unlike rubber blankets, do not include a layer of compressible material.
The coating form itself must be highly compressible, as in coating application the printing pressure must be kept as low as possible.
With a rigid, non compressible layer, the printing pressure will be too high with negative impact on coating transfer quality.
KRUSE VARNICOMP SR, underpacked to VARNIPLATE/VARNIBLUE, has an excellent resilience (the material’s capacity to spring back to original thickness after each compression).
The product has extended durability due to its high mechanical resistance.
VARNICOMP SR is made of polyurethane with a specific profile of peaks and valleys. As shown in the enclosed drawings these peaks behave like a spring when compressed
VARNICOMP SR resilience and the elastic response have superior performance and advantages compared to compressibility in blankets system made of closed cells.
See the three drawings attached.
VARNICOMP + VARNIPLATE (VPL)/VARNIBLUE(VBL) PRESS PACKING:
0,64 mm + VPL/VBL 1,95 mm = 2.60 mm total thickness for MANROLAND
1,00 mm + VPL/VBL 1,35 mm = 2.35 mm total thickness for MITSUBISHI
1,30 mm + VPL/VBL 1.15 mm + 0.80 mm paper = 3.25 mm total thickness for HEIDELBERG-MANROLAND 900 + VPL/VBL 1.15 mm = 2.45 mm total thickness for MITSUBISHI
1,45 mm + VPL/VBL 1.15 mm = 2.60 mm total thickness for MANROLAND + VPL/VBL 1.35 mm = 2.80 mm total thickness for KOMORI and RYOBI
1,95 mm + VPL/VBL 1.15 mm = 3.10 mm total thickness for HEIDELBERG XL105 + VPL/VBL 1.35 mm = 3.30 mm total thickness for MANROLAND big sizes and KBA
2,10 mm + VPL/VBL 1.15 mm = 3.25 mm total thickness for KBA-HEIDELBERG CD + VPL/VBL 1.15 mm = 3.25 mm total thickness for MANROLAND big sizes
