does anyone have rockhopper38 profiles please?
I bought this machine secondhand two weeks ago, When I picked it up I watched the engineer work on it for approx 4 hours replacing the print heads, capping station etc.
Having no idea what was involved with these machines I transported it back in my van 150miles with a big grin on my face. 😀Since then I have had to strip the thing down due to a blockage in the waste pipe which in turn blew a pipe on the capping station and kindly deposited the ink onto the floor.
To cut along story short I have now got the machine printing perfect test prints but from the rip in flexi 7 the colours especially yellow are very dull with what look like tiny black dots combined with the yellow.
I have tried using the mutoh profiles and they are not working for me, I went onto the oracal site and their profiles for the media are not in icc format when downloaded.The machine was running on solvent inks from inktec and I bought the same to try and avoid problems.
Apart from scrap it, use it as a door stop, any advice would be appreciated.
Many Thanks.
Roy.

were did you buy your Inktech inks from, i’ve been trying to source a different supplier but cant find one.To stop blockages, did you get pure solvent from your ink supplier, before shutting the printer down, fill a syringe with pure solvent and tell the printer to do a tubing flush, this will move the head away from the capping station, the pumps will switch on , squirt some of the solvent into each cap, to clean the tubes also put some down the dump tube, this will stop a lot of your problems

Roy,
what version of Flexi, Oracal profiles are PTF files you actually import them into production manager but depends on the version you are using. I’ve run a Rockhopper 38 for 2.5 years on Mutoh inks & its been as been a brilliant machine. Now selling it as i have a Soljet 2Kev

Hi Kevin,
The version is Flexisign 7.Many Thanks

7.6 takes Ptf files which are imported in to Production Manager anything before that takes ICC profiles i may have some on a disk somewhere but can’t be sure.Kev

Cheers Kevin,
Any help would be appreciated, now used about 20m vinyl trying different settings to no avail, decided to call it a day and try again tomorrow.Roy.

You may be the chap that rang me when you bought the Rocky 38.
You aren’t supposed to run full solvent inks through this, only eco solvent or eco ultra inks. Full solvent will damage the pipes and the machine.
My opinion……Scrap it!! If you have wasted 20 mts of vinyl that is only the start! -
the darker speckles are down to the rendering intents used. the individual colours are being colour managed. this is adjustable within flexi.

the inktec inks from what i have heard are actually quite good. they are agressive to the media but relatively kind to the printer. the rocky has metal pipes inside at certain junctions which do seem to cause problems with solvent based inks though. in past experience with the machine in its native mutoh falcon guise, they were problematic even with water based inks at times.
dont give up just yet.

Hello Karl, yes it was me and I listened and respect your comments,
I have also had feedback from other owners since our telecon regarding this type of setup with solvent inks and they have different views.This is my first experience in wide format colour printing and it has been a learning curve, I appreciate what you are saying about the machine and the problems you had to put up with down time costs etc.
Mark many thanks for your comments I will look at at the rendering side and see if that helps.
Like I said the test prints are great its just the rip to printer side.Roy.

It has to do with the ICC profile. Try turning off the output profile and You will see clear Yellow.
You can also play with the rendering intent from perceptual to colorimetric or saturation. In some cases it will help.
But new profiles are needed.
Regarding ink – I think the color densities are too low in InkTech, so printing in high speeds makes profiling quite hard and in some cases impossible to get nice saturated colors.
