The speeds for the HP Latex machine that Stephenedwardgraphic is quoting are from the 310 model (54 inch wide). The Latex 360 is significantly higher throughput machine (neighborhood of ~2x) than either the 330 or 310 machines. The 300 series is also much (like 6 orders of magnitude) faster in...

The place to linearize most large-format printers is in the RIP that is driving the printer. This is true for halftone printers, including the Mutoh machines. I do not know whether that functionality is enabled in the version of Photoprint that you are running, as it sounds like a 'bundled'...

That image shows clear evidence of over-inking of the media (note the areas of shiny black ink). When you lay down more ink than the media can quickly handle/ dry, you are prone to this type of inter-color bleed. To stop this, you would need to either restrict the amount of ink, and/ or...

Is this an i1Pro device or an i1Pro2 unit? See attached image if not sure. Either model is compatible with Windows 8, and the OS drivers load with i1Profiler software, which I am assuming that you used to profile the display with, correct?

Roland technical support does not expire (warranties do), you can contact Roland directly via phone at 800-542-2307 with a valid serial number. The Roland VS Series did not exist at the time that Flexi 7 was last shipping, and that is why there is no driver for that machine in that version of...

In my experience, with the HP Latex machines this issue would likely be directly related to printhead performance. Printing gray involves all colors firing in proportion to each other. If you are seeing color shifts in the middle of the long print run, it would be attributable to nozzles...

The HP L25500 and L26500 (Latex 260) machines communicate various information back to the RIP, along with receiving data from the RIP (bi directional connectivity). To do this, they use ports that other printers don't utilize, and often times these ports are being monitored by anti-virus...

I think you meant advance the media 5 or 6 inches, and not feet (anyone else having a Spinal Tap flashback?).

I am curious about how you feel latex ink compares in terms of uniformity of solids when compared with eco-solvent ink sets? I see in your profile that you have or have used both Roland and HP Latex machines.

Is that vector art?

Congratulations. The experience of changing from a Mutoh Falcon to a 300-series HP Latex should be pure bliss...

The overall throughput of the HP Latex 360 is significantly faster than the Latex 260 when printing on similar medias. This is due to: 1) A Major reduction in printer warm-up time from ~ 8-10 minutes on the L260 to ~90 seconds on the L360. 2) The addition of the Optimizer to the ink set...

Assuming that there is a variant of solvent ink in the printer, you should be able to image onto PVC vinyl, either clear or opaque. Clear media will not provide a white base to bounce the ink off, so you should expect the output to look less vibrant than it would on a white opaque media.

Printing various shades of gray tends to be the Acid Test for any color managed workflow. If there is a problem, it will show up in the grays first and foremost. Changing the ambient light source (illuminant) further complicates the issue, and this can sometimes cause metamerism. It is not...

I have found 3/10 of a second (0.3 sec) to be helpful in several cases.

The place to start (always) is with the printer and more specifically, with it's nozzle performance. For the JV3, run a Test Draw from the printer's front panel. Depending on what you observe in the pattern, it may be necessary to perform remedial maintenance to get the affected nozzles firing...

8 passes is below the recommended minimum pass count for adhesive vinyl on the Latex 260. 10 is the minimum pass count that HP recommends for this media class. This is ink coalescence. It can be controlled through a combination of one or more of the following: 1) Reducing the amount of ink...

This has everything to do with the concept of Device Dependency. Every device in the workflow (your printer in this case) is unique, and this inherent uniqueness is amplified by the differences in environment between the environment where the profile was built (Salt Lake City in this case) and...

Well put.

What I see in the images appears to be more related to 'Chromatic Banding' (aka lawnmower banding) than feed or nozzle induced banding. In that case, I would think that a uni-directional print should not show this type of artifact.
