Banding on Black Background
I am trying to do a large format print for s spider display. The background colour is black but this is appearing with banding. However the text and images print fine unless there is black in them. Any ideas? Its a Roland Soljet pro II.

unfortunately type of media – profile – type of ink and number of passes can all make a difference.
because you say the other colours are fine then i would guess total ink load and or profile.
what is the material etc.chris

The material is Metamark MD-RU 2. The inks I am using are Life Ink Digitl Ink. I have tried it on Metamark MD5-105. I have also tried it on GPPM Matte Photo Paper. The print has also been tried on Bi- Direction and Uni- Direction with a head speed of 250.

same machine but different inks and material to me and still say its a profile issue. your ink supplier should be helping.cheap inks bad profiles = expensive printing, because of waisted media.
presuming all the jets are working and you have checked the media feed calibration,and set up the bi dir settings try 720×720 8 pass bi dir with a max ink load of 220%.chris

I am using versa works. Where can I make the adjustments you advise. Would it be on the printer or in versa works. I have adjusted the calibration feed to -0.45 this appears to give a better output than anything above i.e -0.40 to +0.5. I’m a bit wet behind the ears as far as issues on the Roland as to date I have had no problems so it’s really been the case of load the media select the profile and print.

Hi Im no expert by any means but seem like your head speed is to slow and the ink is maybe drying before the heads pass again try speeding it up a bit i have been using MD5 on my cadet plus but my software is sign lab 8 I’m finding less banding on 750 head speed bi directional 2 ink 4 passes try and 40 deg on heater its worth a try and see if faster head speed helps ?
