Bartender Struggles With Image Quality S’abonner

Bartender 9.4 SR3.

 

I'm looking for best practice on getting images to print properly on thermal printers, something I have struggled with over many labels, and after testing a multitude of formats.

 

I've attached a sample image in PNG format: badimage.png. It's clean and looks nice.

 

badimageprinted.png is what it looks like on a label, including some clean text printed above, proving that the printer is capable of printing nicely. This is at 100% image size in the label template, though if I try and shrink it down to, say 30%, I get similarly bad results.

 

This is a Printronix, but its model is irrelevant, as I have the same issue exactly on Zebra thermals.

 

The only image format I seem to be able to get Bartender to print cleanly with is .wmf or .emf (vector) images. Whenever I try with bmp, png, jpg, and whether I do 100% or not I invariably get severe pixelating, as if Bartender has wildly compressed the image before sending it to the printer.

 

Any tips?

As best practice we would suggest importing the image at the size it will be used, avoiding any size transformation in BarTender.

 

We use LeadTools as the image processing component in BarTender, which unfortunately is a black box to us. Note that on later versions we've updated this component to its latest version getting much better image processing results. Could you download and test our latest version (v10.1) from the below webpage?

Thanks for the response.

 

Before upgrading, I stumbled into this thread: http://seagullscientific.invisionzone.com/index.php?/topic/587-picture-printing-quality/

 

It turns out that i can correct my issue simply by setting dithering to none. it was set to Half by default, and thus the undesired blending effect. I'm ok now :)

I discovered that Dithering:None improves my image quality. However, I can't seem to make that setting permanent in Printer Preferences . My printer is a Zebra 105Se(203 dpi). The driver version is 7.3.7). I am running Windows 7 Pro (64-bit).

  Can someone give me the right incantation?

On further review, the ruling on the subject is reversed: I am the IT guy, not the BarTender user. I learned that Printing Preferences are saved with each label. Thus the solution was to instruct the user on how to change the dithering option and to save the label after doing so.
