After the Press roller is pressed to the drum, the printing paper is gripped firmly with the drum and Press
roller, the Guide roller is released from the Timing roller. This is called
"escaped"
. Escape timing is within a
period when the printing paper is conveyed about 10 mm after it is gripped with the drum and Press roller.
(4) Escape the Guide Roller
¡
When the timing is too late, the printing paper is gripped at two places too long. Thus
master elongation and slippage occur.
¡
On the contrary, when the timing is too early, the printing paper is not gripped at all, and it
is not well settled. Thus creasing of paper and dispersion of the printing position occurs.
