  1. Hp Latex 360 Prints Grainy

    Dear HP-Latex users suffering from „plasticizer migration“, Grainy prints are a phenomenon that returns again and again on HP-Latex systems. The rumor that this problem is caused by plasticizer migration was started by HP and is still used (see various topics on this forum) but is absolutely...

  4. Hot or Cold Laminator

    If you want to laminate vinyl on vinyl cold lamination leaves micro air inclusions showing up as a silvering effect. Laminating at about 100 F will deal with this.
  5. Roland RS-640 Strange Jpeg Print

    sorry for the late reply, this one slipped my attention. Thereason you see the water color in the pate but not in the text is that in those areas where you see it happening the amount of ink is much higher in the reddish/brown color (you will have serious levels of CMY here) than in the red...
  6. Monomeric Laminate on Polymeric Vinyl ?? First newbie Error!

    The monomeric plasticizer will migrate to the polymeric plasticized film. So you will see excessive shrinkage of the monomeric film over time and possibly swelling of the polymeric film. Your adhesive of the laminate will soften and probably that of the base film too. You might see Separation...
  7. Roland RS-640 Strange Jpeg Print

    The images show an high flow of the inks indicating that you are depositing too much ink for the printer to dry. This can either be the fact that you are using one profile on 2 different printers (probably a VP 540 profile) or the heater of your RS 640 is not functioning well. Try to find...

    Oracal 651 Matte Dark Green or Forest Green come with a permanent adhesive. The 631 series mentioned above comes with removable adhesive.
  9. Banding On One Side But Not The Other?

    Check the media temperature across the width. You are probably having a lower temperature on the left side which is causing the banding. Roland heaters often show these kind of problems.
  10. banding question

    Assuming you are printing bi-directional you are probably printing a little too fast for the ink to dry. The time between 2 layers of ink is the shortest on that side. It could also be the heating of your Printer; do check the media surface temperature over the width with an IR Thermometer.
  11. out gassing solvent prints

    General remark about drying of solvent printed pressure sensitive vinyls: Most solvents rapidly migrate through the film into the adhesive, specially ecosolvent inks. For proper drying 2 things are important: air movement over the surface to enhance evaporation and reduce the solvent...
  12. Avery wrap laminate dol1060 vs dol1360?

    Both films are made from the same formulation so the only difference is the amount of vinyl you are buying. It is most probably the same film as used for transparents in the other cast-series (at least that is the case in Europe), only a difference in thickness. The 4 years durability compared...

    Todd, You best take the laminate version of the material you are printing on. That way you avoid problems with different shrinkage levels and plasticizer migration. good luck
  16. Did I get a bad roll of media? Orajet 3751 RA

    These kind of problems are typical for cast film constructions and are related to a problem with the liner used. Thing is that during the manufacturing of the liner some silicone transfer takes place from the silicone side to the backside of the release paper which later is partially transferred...
  17. What lam for contravision?

    Lam for contravison Biggmann, I suggest your expensive laminate is on a polyester liner, the Avery DOL 1360 on a paper liner. On the polyester liner your film+adhesive will be crystal clear, on paper it is somewhat structured by the paper. Applied directly onto glass both give a clear result...
