Selling our Presstek 52Di - as seen in pictures, this is a mint condition press (Presstek will back this statement up) with low impression count, service contract protected since new. 2007 model. Ground floor location, easy removal options. We have some video footage of it doing test runs...

Have had some samples of our work done on a 5600 and were really impressed, we currently run waterless offset but our runs are getting shorter and we also want more diverse substrates which we can't do on the Di. The samples were really impressive, 100% colour match to our proof and done on our...

Long story I'm afraid... We have had a Presstek Di52(waterless) for the last 8 years, started out with issues (hence my user name!) It came with Toyo inks as they were recommended for it, but the colours were useless and no good for euro/ISO colour printing, being a Japanese ink set. Soon...

Looking for help again, we have finally had to resort to using Toyo Aqualess MZ inks on our 52Di press as all other brands have now failed through one reason or another :( We have managed to get acceptable results on coated and satin coated stocks but it refuses to run on uncoated stock - we...

As title really, is there a shelf-life for offset inks? In particular, waterless inks. Still in sealed tins of course.

The setup - B3 Waterless Offset machine. Can anyone tell me why I should not alter my ink order from K-C-M-Y to Y-M-C-K?? What are the possible side effects of doing so? Is there a specific reason for running K-C-M-Y? Many thanks Dave

I am trying to find out what inks everyone is using on their Presstek 52di, also what roller temperature setting, if you could let me know the following answers it would be very much appreciated. What inks ? What temperature ? Do you adjust temperature during the day ? Do you run to any...

Does anyone here know if the plate cleaning wipes used in the imaging system on the 52Di contain silicon oil or not?? Also is anyone out there running this press with Stehlin-Hostag "Reflecta Dry" inks??? Thanks

Hi all, this may already be in existance on some presses, but i dont know of any that have it. Is there any print related reason that Infrared temperature control should NOT be a closed-loop system. I.e. monitored and controlled automatically to give a preset stack/sheet temperature?? Do not...

Hi all, We have a Presstek 52Di press which is performing well, it is coupled to a Harlequin Momentum Rip. I am trying to figure out if there is abetter way to perform press calibrations, this is what we do at present... Print test charts and linearise the press, this curve then goes into the...

Hi all, What difference does colour sequence make to a job? I know it does make a difference as a print engineer proved it with a hard-to-match purple when he swapped the Cyan and Magenta around and it worked much better. We are still printing K – M – C – Y as he left it but what would Y – M...

We have a Harlequin Rip, and it is doing odd things with the export data from our press-sign software, here's the scenario... Create a linear tone curve, set 60% at the 50% point on any curve, extrapolate the rest of the curve and save. Edit the curve from calibrated and enter 45% at the 50%...

Hi all, Considering the following.... Same paper, same press speed, same ink set, same plate manuf, same blankets what sort of variation in TVI would you expect to see from job to job on a press? I am guessing at it being very low <1-2% ??? Dave

Hi all, On all of our previous machines the ink vibrator roller contacted the duct roller once for every sheet on a fixed cycle, nice and simple and has work for countless years. We now have a Presstek 52DI which has the default option of intermittant ink vibrator control based on a set of...

Hi all, i once had a figure for the optimum stack temperature when running with IR but have lost it, anyone know what sort of temperature we should be aiming for on the stack probe? I know it dangerous if too much heat is put into the stack and have even had tales of stacks spontaneously...

Hi all, I'm looking for information from printers running to ISO12647 standards on machines like Heidelberg SM's etc with full integration of colour control and so on. We are running an inplant print room with a waterless DI press, and using PressSign by Bodoni software to check & verify a...

Hi all, in line with another thread i have running, i am looking for some information regarding press curves. We have been struggling with flat, lifless print for some time now, and managed to get by with tweaking tone curves etc. I have just been studying a chart from Gretag Macbeth listing...

Hi all, I run an in-plant printers in Hertfordshire, UK, we have a Presstek 52Di with a Momentum / Harlequin Genesis v7.1 rip with colour-pro enabled. We are trying to find out how to profile the press, so we can improve colour matching. Being in-plant we only use a couple of papers and one...
