There are lots of conventional and thermal plates available, each with its own set of specifications. Thermal plates (same goes for CTcP) can be very different in emulsion coating sensitivity, guaranteed run length in printing, uv compatible or not, resolution range, pricing, local availability...

Hi ighodaro, You clearly have a bad batch of plates - either a manufacturing problem or plates being stored in a VERY humid environment for a long time. Interleaf paper creased or stuck to plates indicate too high humidity. I have never seen anything like this myself as I have only used Kodak...

Poor focus, insufficient laser intensity or low preheat have to do with excessive image wear during the run. Emulsion coming off the substrate I believe points to a bad batch of plates. When you say it peels off how does the plate look exactly, is it in large random areas ? Just short streaks...

Violet plate processing is as stable as you care keeping the machine within specs. I agree violet processors do need more maintenance than others but again, has nothing to do with stability. Linearization is the way to go. The man says they have a prepress bureau there, no offset machines of...

Evir, you are looking in the wrong place. The segmented drive system cannot, repeat, cannot seize this bad without putting an encoder or drive motor error. Your banding as I see is most likely caused by the film processor rollers, check the roller drive gears in the dev section they must turn...

The Avantra max addressable resolution is 3600 which also tells me ruthndull does not have much control over what's happening in the prepress/imagesetter dept.

You should have posted pictures of the films and or plates. Printed sheet is not relevant. What angles is you spot colour plate ? K seems 45. Did you see artifacts e.g. banding on previous jobs ? Off topic there's no real benefit exposing film at 3600 for your Itek ... the 150 lines screening is...

Bren, the plate should come up clean if properly processed. What type of plates do you use ? Rinsing the plate again then gumming may improve the hydrophilic properties of non-image areas but have little to no effect on image.

Common problem for recorders fitted with internal air compressors. Replace filter elements. Do not attempt cleaning them, replace. Check the entire comp air circuits for leaks (old plastic tubes get loose). Make sure autodrain valve works properly. Take out, take apart and clean the air pressure...

Is the image ok ? Is the shifting always the same or random ?

LOL this is "best of the year" !

It seems to be about driving indeed... but nothing to do with Heidelberg Druckmaschinen. Coincidentally this car dealer company is based in Heidelberg Road, Melbourne. False alarm.

Man should pay attention to the amount of alcohol 'she' consumes, too

Shot in the dark could be heat generated during coating polymerization - what the heck varnish did you use and why hasn't it been cured completely ?

I say there's something really wrong in your printing process.

Film alignment fails during forward and reverse movements. Clean input rollers and dancer steel bar, make sure the film is loaded properly inside cassette, load film carefully.

Gordo you may get false results. People using several offset machines will respond with second option, they will use different plate curves for coldset, heatset and sheetfed machines because dpi and screening is (usually) not the same.

Thingamabob heavy iron - $150000. Installation fee - $8000. Advice from forum fellow who thinks he knows how to repair the said iron - priceless.

In theory it's doable but the board has to be checked for further damage in that area ... this multilayer PCB may be beyond repair. The blown circuit is an obsolete bidirectional 4-channel interface but there is a modern equivalent alas very hard to find. If previous EAK's failed like this one...
