Thomas, in reference to your customers need to reduce makeready waste on his
web equipment, I am curious about a few items. The assumption is that you
are talking about 10,000 cutoffs per run for makeready, then run spoilage is
on top of that, correct? If that's the case some of the previous suggestions
concerning maintenance would be the a great place to start. Manual ink
settings most likely are the most consuming aspect of your makeready, by the
time you achieve color balance (depending on makeready speed) you've chewed up
a lot of stock!! This may be an area you would consider remote ink fountain
control, but with the age of the presses maybe not viable. With our companies
experience in the 1/2 Web market, 2 heatset 4/C & 5/C approx 12 to 15 years
old, with retrofitted ink control we are averaging 5,000 to 7,000 cutoffs per
4/C makeready at 18,000 cutoffs per hours. Our consideration for ink controls
does stem from the presses ability to "print a great dot"
so our retrofitting worked for us. You can draw all the curves you like, but
it will be your press crew that will make the difference!! Also, at what
point do you start "keeping" for count? too late? Press competition also adds
to the efficiencies. If this seems vague or not "technical enough" think
about it for a bit, and just watch what goes in to the makeready!!
