Are these positive or negative plates? My theory is: Somebody has lubricated the lead screw, resulting in the lines going away, however, they applied too much lubricant, which is now flying off the lead screw onto the surface of the plates. Of course I may be totally wrong :)

The lines look too close together to be a laser focus or power problem. Try applying some light silicone oil to the lead screw and see if the problem goes away as this can be caused by a dry lead screw.

You would need to calculate the circumferential increase in print length when the blanket is mounted, we used to do this with rubber stereos for continuous stationery printing, setting type in hot metal with the appropriate reduction scale, pressing onto a flong, then transferring to a rubber...

Wherever possible we run long grain on press, meaning the cutoff would determine the sheet width rather than the reel width, in some cases short grain may be required for binding requirements. Either way, we expect sheets to be within 1mm of specified size in both directions. Most mills will...

I have never seen an option for this in Prinergy. There is Web Growth Compensation in Preps, but not directly in Prinergy. We used to be able to adjust each separation in Brisque, providing the output device supported variable resolution, but the function does not exist in Prinergy.

My son has just completed his Masters in Science Communications, I will pass this on to him as I am sure it will be of great value in his future endeavours :)

Easiest method is guillotine creasing: Set the backguage of your guillotine to the value of edge of sheet to score, bring down the clamp and tape a sheet of strawboard, box board or whatever you call it in your part of the world to the bed outside the clamp, and hard up against it. Lift the...

We haven't had a call for circles, but shouldn't be much different to the rectangles.

No problem with them here in Australia, we get all sorts of calendars, tradies advertising etc with magnets through the mail regularly.

We do this all the time. You can buy sheets of self adhesive magnetised rubber pre cut into squares or rectangles of various sizes. Peel them of the backing sheets and apply by hand. 10,000 would be 6 - 8 hours work for 1 person, get a few hands on it, you'll get it done in no time. If you have...

I can't speak for flexo, that's a completely different world, where trapping, from what I have read can be quite a can of worms. As far as offset goes, providing your machines are well maintained and print in register, most of the time trapping light colours to dark colours with your chosen trap...

Ink tends to have a smoother appearance as a screen than it does when printed as a solid, and helps to reduce the infamous Heidelberg gear mark 2/3rds down the sheet.

It's an option in Prinergy I always thought it was to achieve a smoother result rather than to save ink

Not really weird, you cannot output blends across different colour spaces

No, there is no substitute for a competent tradesperson
