As a Cron Technician, I would say that machine is reliable in terms of imaging quality, Auto feeding is good if maintained and cleaned properly, otherwise you'll get issues like scratches. As Chris said about image centering, it can be easily corrected with software parameters and not a frequent...

Get it made from a machining shop.

Depends on the run length, if a short run job, the percentage will be much higher and as the job run length increases , percentage will drop. Type of jobs and number of colors also determine the wastage.

If you find a better place, let us know too....

Here in our country the offline coating units are mostly made of an old press and aftermarket UV driers. The UV coating is transferred through ink fountain to rollers, plate,blanket to substrate . ​​​​​​So as alibryan said, the roller coaters apply higher amount of coating layer to the...

Thank you all for your input. Another question, can coated or uncoated spray powder make any difference in UV coating or both types can cause similar issues?

What kind of issues we can get in offline UV coating if a job printed with conventional inks and anti set-off powder was used?

It can be done without any damage to the press, as Alois mentioned, keep your roller train disengaged if it is an option on your press, otherwise you can turn off the roller oscillation and put some roller lube in ink train. This will prevent damage to your rollers. Regards

Even though the material is same but the surface tension may have increased due to lack of corona treatment or if its an old stock. Usually corona treatment last not more than a year. If this is the case , the ink will not adhere to the substrate even though the ink is cured properly.

Looks like a bad batch of plates. usually the thermal plates are not that sensitive to light. On the other hand CTCP or UV plates are more sensitive to light.

Changed only two driver boards in 3 years.... Its a very stable machine unless something is wrong with your power outlets.

Hi Chris, As a service tech for Cron CTP systems for the past 3 years, I've never seen diodes failing in cron too early, We have installed 14 machines here in the past 3 years and only 2 or 3 diodes failed totaly. You can still continue production at slightly lower speed. Yes the...

Polar and Wohlenbergs are the best.

You can invest in CRON CTP , much better than other Chinese offerings.

Pakistani? :confused:

Thanks Aois, I'll check the device settings again, lets see if it works or not.

Dear Alois We do have a conductivity meter for fountain solution conductivity measurement Tech Pro 2 but it does not measure the developer. We need a specific model number that anyone is using. Regards

Hi All, I want to know which specific instrument you use to measure developer conductivity in processor? We are looking for a reliable instrument. Regards
