Negative. In several ways. That is, the answer is negative. You need negative plates i.e. photopolymer violet sensitive plates. Violet laser (405 nm) platesetters such as Prosetter can only expose plates having sensitivity better than 60 microJoules per sqcm (typical range is 40 to 55 µJ/cm2...

Hi gordo, most violet plate manufacturers have shrunk down their plate size range offering or even removed some plate types from their portfolios (i.e. ProV) because of low demand. Fujifilm has a strong presence in the UK (and Agfa to some extent), but I wonder why the article disregards other...

You can only disable the offset punches from printing machine setup. The registration punches cannot be disabled.

I guess Impostrip Pro does what you need, call Ultimate Technographics.

I need a copy of the HQRIP-510PC (v.6 hqn) for Screen please, we have the licenses and dongle but lost the cd. I need to replace the host computer with another and cannot reinstall... Thank you !

Celebrate diversity !

Step 1 : open your page setup manager and edit each page setup at a time by checking the checkbox to 'enable feature', then select 'use filename as jobname' from the pulldown menu. Step 2 : edit each page setup to 'Configure' the tiff generation ; in the next window called 'Tiff configuration'...

Hagar_uk advice is spot on. Look for a 4300 or 4600 unit with low mileage and ask for a test.

Aqazi, the number of available grey levels depends on the rip software your customer uses. You didn't mention what software it is. All modern 'super cell' screening solutions based on Adobe library or harlequin or else do minute changes to dot shape as gordo described already, we perceive this...

As far as I know there is no technology remotely comparable to imagesetter film exposure to achieve ± 4 mil spec using sheet or roll fed substrates. Some of my customers had no option but move to DTS machines.

Check emulsion side. Check roll year of manufacture or 'best before' stamp on label, the film may be old. Replace with a different batch.

How much lighter is the image ? Make sure the film is red sensitive and check the roll emulsion side.

What harlequin (OEM) do you have ? Is the cip3 option licensed to run ?

The polarizer is a rotating wheel reducing the laser beam intensity according to the exposure level required. This disc is part of the Spot Generation Module on the carriage and not easily accesible. It seems the motor or polarizer sensor has a problem. Haver you tried restarting the imagesetter.

Correct. Violet photopolymer plates require 35-55 microJoules/sqcm, that's less than 60 microwatts reading on a laser power meter right above the plate emulsion. Some digital UV plates are sensitive to UV up to and including visible domain 400-405 nm but they need 50-60 mJ/sqcm we're talking...

Should be ok just go slowly. Put path down.

I reckon you meant violet plates since you refer to Palladio. This Agfa ctp was indeed based on the 2055 platerite but cannot be retrofitted with an infrared laser instead of the 405 nm visible wavelength laser diode such an advice is unprofessional.

Seems to be Exe04 excessive current in the LD driver board 4, if so check the laser diodes Iop values and make sure flat (FPC) connectors on cables going into the RH are correctly attached as sometimes they make poor contact forcing the driver to increase current to the limit - diode...

ctptech, e04 is meaningless, the code must be 4-5 digits depending on model and firmware so ask your customer for the complete error code or post a screenshot of information > error log display. Can be anything really ... exposure head problem, leadscrew positioning fault, data path problem...

I would put a USB microscope on the plate. What offset machine do you use ? Who checked the machine ... the pressmen themselves ? I say Alois is right, leave the affected plate(s) on the cylinder and check the blankets for damage or metal flecks possibly embedded into rubber using a magnifier...
