Printing blank page with Transparency on - T5270D Plotter

[Anonymous]

I've only found the below on this issue when transparency is turned on...other ones I've found have been related to the DPI.

Problem we are having is like the below thread but the 5270 doesn't have this setting. Wondering if anyone has had the issue on this plotter and knows the fix?

Thanks!

Hi,

>> other ones I've found have been related to the DPI

In general it depends on the memory within the plotter available for a plot task.

If it does not have enough memory it stops at some point and the rest of the page stays white.

Lowering the DPI means the plotter does not need that amount of memory. So that could help

You might also try to plot with transparency to PDF and then send the PDF to the plotter.

Sometimes it helped to uninstall the existing HP driver(s) and install the HP Universal Plotter driver instead.

I would assume though if the user can print it fine with that option off...Then it has enough memory available to plot the drawing. We tried it with just a small drawing with it on...much smaller than ones we were trying it on...and it wouldnt print.

Sorry, not correct.

With option off the plotter can plot vectors, with transparency option ON it first have to rasterize the content (calculate mixed RGB-values based on transparency for each pixel) and that needs a lot more memory.

Ok that's true but like I said we printed a much smaller drawing. like it it literally just a box drawn on the page.

Which paper format?

C , D, or E size

Hi,

C-size: 18x24 inch * 600dpi * 4byte per pixel (RGBA) = 18*600 * 24*600 * 4 = 622MB for one image (uncompressed) to calculate overlaying vectors with another transparency.

How much memory does your plotter have (free for new jobs, not just the build in size).

Try it with A-size and reduce the raster density to 200dpi, if it then have issues too I would recommend another plotter driver.

Did an A size this morning with everything turned all the way down (DPI, Print Speed). Still got just the lines we were getting before.
