But there is a tolerance for the proof as well... right? I mean if we took proofs from 10 different printers that were using the G7 process would they all look and measure the same? Are they supposed to?

What if our G7 proof seems to have a warm feel to it? Should we change our press sheet to match that even though we feel it is too warm? Or should we tweak the proof? I would love to see other G7 proofs from other printers as i'm sure they will vary greatly based on how wide the tolerances are.

Yes, sorry for the incorrect terminology. Our press sheets colorimetrically are pretty good. We have had to resort to making proofs based on the press sheet and not G7 in the past but in this instance we are talking about the proof was made both ways and looked fairly similar but still not the...

How do others rate their proof to press visual match when profiling with the G7 methodology? Other employees say I am too picky and want a perfect match that is unobtainable. I have been trying to get a press sheet and proof match from another printer for years now but it seems like other...

I am just wondering how others calculate the spine width for perfect bound books for a variety of paper types. We are coming up short on jobs using our current calculations especially on dull stocks. Any help is appreciated

We are having issues printing solids on our 6 color komori. I have tried to print this solid (a full sheet size solid) in three different units with the same results. We are seeing streaks about a quarter of the way up the sheet from the gripper that you can see an outline of the colorbar in...

Yes... We had to pull a job due to these craters on one side of the sheet. Then put in back on with new paper and had pretty much the same thing. It's a shame that we as printers are held to certain standards when the foundation of our product (the paper) is so erratic.

I am looking for information regarding printing lenticular on a non uv press. We have found necessary prepress software but as far as how to print it (non uv) we are a little in the dark. What material do you use to print on? Where do you get it from? Any information or experiences is much...

Hi all, I am currently revamping our OSHA programs and wanted to see if I could get some samples send to me of some programs you use. Currently I have it broke down into subcategories i.e. safeguarding, HazCom, walking and working surfaces, emergency evacuations,etc... I have to change the...

We are going to run a skid compiled of various brands of stocks later this week. The paper that is showing the shrinkage feels brittle and the cover stock was cracking when we were binding it. Luckily it was a perfect bind job and not a saddle stitch. Will keep you all posted...

We are having this issue on both of our sheetfed 40" presses. Paper guy was in today and claims he has never experienced anything like this. It can't only be happening in one shop with this paper...

We are currently rearranging our pressroom to increase efficiency in our workflow and I was wondering if there is a better way to store the plates before they go on press. We currently have a cabinet with 25 drawers that pull out that we use. Sometimes we get scratches if someone puts too many...

It is happening on a stock called Titan (coated and dull)... I believe that some of the issue is the enviornment in our shop has been off a little due to our humidifiers not working correctly. The problem is it isn't shrinking consistantly so it is impossible to account for it in bindery...

We recently ran across a stock that seems to be shrinking while it dries. Sounds crazy but the crop marks are measuring 1/32" to 3/64" shorter on the sheet than the plate both ways (gripper to tail & side to side.) It is happening on cover stock as well as text weight but only on one specific...

Make sure you rack the job in small lifts as it will offset easily with only medium coverage. Also, I agree that some sort of oxybind ink should be used if you want it to dry. We have printed on really light translucent stock and it was tough to even get it to lay into the delivery without...

When we reprofile we start from scratch with new icc profiles. The "tweaking" is when we update the G7 curves. We have used the spot on software and you are right it is great for tracking. Our free trial ran up and my company couldn't afford it at the time so I have built an excel spreadsheet to...

Just trying to conduct a poll regarding how often other printers reprofile or tweak their profiles. We profile to G7 specifications and usually tweak every couple of months and reprofile if some big change occurs i.e. new ink or new rollers. Due to many variables press conditions move slightly...

Calcium would come from the paper... These are all very interesting suggestions... We are in the process of tracking the way we are doing things i.e. calcium fixes, blanket to plate pressures, and we are going to start hitting the plates with fountain solution before printing especially on silk...

LoopyG... I think your right... I looked at some trends today and noticed that it happens mostly on our 1st and 2nd unit on our 8 color... It also happens more frequently on silk stocks so I am thinking that paper dust buildup gets on the blankets and wears out the plates. We have an...
