  1. Thoughts on Hp latex 570?

    The Latex 570 was a current product between 2016 and early 2021. It has 3-liter ink boxes, and as such, was intended for an average production print environment of at least 5 rolls per month (150ft). This amount of print should help ensure that the inks are being consumed before they are expiring.

    Some hairs or fuzz is likely attached to the carriage and is dragging through the wet ink, causing it to smear. Remove the maintenance cartridge, power down the printer and gently move the carriage over the right hand door. Look at the carriage bottom with a flashlight and remove any stray hairs...

    Overcoat is an anti-scratch agent. It does not protect from potential chemical attack from gasoline or other harsh cleaning chemicals. Laminates are needed for this.
  6. HP Latex 360 Bleeding Colors

    The average longevity is around 4 liters, but the position of that head is leftmost in the carriage, so it can be damaged in the event of a media crash. The Service History Report or DD test can tell you how many nozzles are out on each head.
  7. HP Latex 360 Bleeding Colors

    Check the status of the Optimizer printhead (PH1). If it has jetted several liters or more (or has a lot of nozzles out), it could need cleaning or replacement. You can check this in the printer front panel, under the Ink / Printhead Icon.
  8. Choosing a - HP Latex 630W or Roland TrueVIS VG3-64 eco-solvent?

    The Latex 630/ 700/ 800 Series are referred to as Gen4 printers. The Gen4 inkset contains an anti-scratch agent that is separate from the other inks, called Overcoat. It should generally be turned off (disabled) when printing to a media where laminate is being applied after printing. Benefits...
  9. Choosing a - HP Latex 630W or Roland TrueVIS VG3-64 eco-solvent?

    Interesting that you mention the longevity of solvent vs Latex inks for wrap applications. The 3M MCS Warranty covers HP Latex inks for 7 years (zone2). The same MCS Warranty covers Roland Trueviz TR2 inks for 5 years (3M IJ180 with proper laminate in each case). Here is the link...
  10. Choosing a - HP Latex 630W or Roland TrueVIS VG3-64 eco-solvent?

    Does white ink have value for you? If all you ever want to do with the printer is print onto white medias, typically the answer would be no. On the other hand, there is a world of non-white printable media (clear/ translucent/ colored/ metallic etc) where white ink can add tremendous...

    Designate one of the printers as the reference printer (target). 1) Reference printer: through the EWS/ Embedded Web Server (browser-based) interface, export the media preset for the media being used (OMS file) and save it to a PC on the network. 2) Through each printer's EWS, import the OMS...
  13. Review of the Roland LG-640

    All printers with white ink have some type of ink recirculation system for the white ink, but as you state, most of these are not 'end-to-end' recirculation. This means that only a small amount of the ink is being recirculated, and not the entire white ink supply. This requires that the printer...
  14. Care to share your Epson experience?

    This appears to be horizontal banding. If you have already performed the media feed calibration, you will need to significantly slow down the print speed by using a higher pass or printing unidirectional. Perform a search- many others have reported the same artifact, particularly in blue solids.

  18. hp poster paper

    Gen3 Latex printers can have challenges with printing to certain paper-based medias. There are papers which ran acceptably on Gen1 and Gen2 Latex which will not run on Gen3 (HP Photo-realistic poster paper is one). The new 630 Gen4 is easily the most robust Latex paper printer to date. In many...

    Make sure that the specific poster paper you are using is on the HP Media Locator. There are papers which can react to the thermal energy being applied in the cure unit by 'tenting'. The middle of the media can begin to lift and cause ink smears in the cure unit or with the carriage. Many times...
  20. Color Match

    Accurately reproducing any color of automotive paint with any wide-format printer is virtually impossible, for a host of reasons. Printing to clear films can help in certain cases, allowing the paint color to be seen through the film, and inking areas that contrast with the paint color. Opaque...
