I've used, over the years, inks from Sun, Hostmann (the old sprinter 3, rapida, reflecta and resista) Innovation and now using Saphira PR100 Plus medium tack directly from Heidelberg. I'm really not loving the inks anymore and find they just don't provide the same level of rub resistance they...

Does anyone here have extensive knowledge of the Technotrans Alpha-C found on the 2006 Heidelberg SM74 (4+L)? Specifically, I am trying to figure out why the pump that powers the roller chillers continually faults and stops pumping. I get the error "F070 - T-Circ. Water Lack" and the pump ceases...

The press is a 2006 Speedmaster SM74. The press itself runs great and the feed seems bullet-proof, except this issue we seem to have on 19x25" sheets. It happens on all text weights (and happens less frequently on anything heavier then 80# gloss or 70# uncoated text) The corner of the sheet...

First let me start by saying the press has been installed for about year now and I've been operating it for about 9 of those months. I spent 11 years prior to that at another company operating a Manroland 305 and so this is my first experience with an SM74 (previous experience on Heidelberg is...

after over 10 years of using the same powder, we've come into far too many issues lately and decided to try out different slightly larger size powder. we've decided to move from a 25-30 micron to a 30-35 size. our roland 300 has a graphix hitronic S unit and the throat at the "hopper" for the...

I've been trying to figure out a new ink-set to try for the last few months. In general we aren't very happy with our current inks from H/S. They were great for the longest time, but within the last year or so have had real issues with batch consistency and issues with dry times. According to...

my press has an intermittent problem where it will sometimes not forward sheets through the feeder. i'm not really sure what else to do at this point. occasionally, while starting a new job it will just refuse to grab and forward a sheet out into the feed table. pickup suckers work fine but...

can anyone give me the name of a Canadian supplier/rep for Toyo sheetfed inks in Canada? thanks in advance!

i'm curious if anyone is having good luck with it. how about the all-star ultra?

we've got an alpha.d that was equipped in '99/'00 on a manroland 305+L for the longest time we've been off of dosers, and pre-mixing fount in a bucket and dumping it into the tank. cant seem to get the dosing working properly. at some point a doser crapped out and after replacing it, it never...

can someone please explain the difference between a speedmaster SM102 and a speedmaster CD102? having a debate with a co-worker about this. neither of us know.

i'm just a pressman, i don't know as much about plate technology as maybe i should but, is the lp-nv2 considered a shallow grain plate?

our company just acquired a smaller shop and we brought in all their equipment. one peice is a single colour GTO52 (i'd say somewhere in the mid 80's to early 90's model) anyway, just wondering if there's any quirks/tips or any other things to know about this thing? just wondering. Albert

we had a rep in from The Printing Ink Company/Rycoline who insisted we try their stuff. he gave us some sample pails of coating and a couple of cans of each process colour. the inks are: Emerald Series (eco friendly) Diamond process CMYK ISO 2846 compliant i've never even heard of this ink...

all rollers are set damn near perfectly in spec. (forms to plate and osc. all riders/bridge rollers the correct pressure) all pneumatic rams to engage and disengage rollers are working properly, my auto wash and water for the roller wash are both full and both spraying properly and all washup...

for years we've used 25 shore "a" and let them get as high as 32-35 before changing them out, however i came across the july/aug '99 issue of gatf world at work lastnight, that has an article about alcohol free printing where they insist 18-20 shore "a" is what it should start at for better...

any ideas as to what would cause a large difference in temperature between the technotrans unit and the water pans in the press? also, a large difference in temperature between waterpans at each unit? the technotrans itself is set for 10.5c and should therefore be about 11.5c when it enters...

if so, do you use it or do you wash by hand?

can anyone point me in the right direction for this? just curious about the use of alcohol in printing here in ontario.

i'm looking to try some other chemestry. not very pleased with our current etch/sub combo. we've been using it for years but it seems to just be getting worse. i'm not going to get into the issues that i am having but i am looking for a change. we're using fuji/anchor emerald jrb etch and...
