Canon IR C5030i Gray veil around letters

Re: Canon IR C5030i Gray veil around letters

The text is Black only. It is printed sharp. When I Print in graphic Mode the letters where in CMY. But all the text has no shadow. When the text is printed in one color, C M or Y there is also no shadow. Only When black text is printed there is a shadow behind the letters. I don't know who I have to look to solve this Problem.

Install ColorPic software on the users computer to hover over the pixels and see what the EXACT color space is on the Text!

ColorPic, The Desktop ColorPicker Software



PS--by the way, what is the file format of this graphic/document? I'd be interested to see the "unadulterated" file personally!

Hello,
In the appendix the doc file, the original document. And a picture with ColorPic on the letters. Printed and edited with Word 2016.

Hi, and Thank-You for the Document!

I viewed the document with ColorPic and it looks ok!....I also printed it out on a Savin C5050 (Ricoh) and everything appeared ok! The only object that appears to be a graphic, is the logo in the upper right hand corner...the anti-aliasing of the text in that graph is a little bit jaggy, possibly due to a lower resolution! Is this complete document before being sent to print is it being rasterized by the print driver?...if so, that might explain the "halo" effect artifacting! Does it happen only from this one computer?...or does it happen from other computers?...and were you able to see with magnification on the actual paper if the text is truly black or process black?....sometimes you can look at an angle to the paper and see if the text is raised up slightly, which would indicate a process black! Keep me posted!

Re: Canon IR C5030i Gray veil around letters

The effect occurs from all computers. It is also under magnification pure black, it is not composed of CMY. Also, the print is not raised up.

I have printed an test sheet and scanned that in high resolution. You will see that only black text has this problem.

Thanks for the scanned sample!...the halo/shadow of the text is most noticeable on the graphic on the top right corner company logo...and I do see a slight bit in the body text but not nearly as much! The halo in the graphic...is the graphic jpeg?, bmp?, tiff?, eps? Some graphics, and I know the bmp (bitmap) allow what is called an alpha channel to make the background of the graphic "transparent" thus allowing you to place the graphic on any color of paper without a printed block of color behind the graphic. Seeing this "noise" this pronounced around the graphic element leads me to suspect that the print driver is not handling the transparent alpha channel correctly, thus allowing "noise" to be printed around the text of the graphic. It is also possible that this alpha channel issue is affecting the haloing around the other text on the page too. Have you tried saving/exporting this document as a flattened PDF? If you need a PDF "printer" I can recommend Bullzip: http://www.bullzip.com
You can download a free version there! Sometimes creating a PDF can straighten out these kind of weird issues! Additionally, does it ONLY occur on this particular document??? Keep me posted!



PS--I looked at my hardcopy printout of the document and I can see a little bit of the halo-ing around the graphic element in the top right corner....but, as I mentioned, the print driver you are using might be causing it to be more pronounced and obvious to the naked eye!!!...and I just noticed in your scanned document, the section with "-> Falls die Frau Schoeler...." the text is ALL YELLOW!!!...what's up with that (should be black)?!....and the text right above that is RED...and it should be black?!

I changed the file accordingly and printed the text in different colors. Also attached the document in printed, which I had before as Annex. The one with the logo is not so bad. However, the shadows behind the black text are much worse. You will see the shadows behind the phone numbers, for example at ...594060, or in the blue area, at "Bei Problemen mit..."

Is this a scan of the document after it was converted to PDF and then printed???...and I do see it in the blue area...it looks like pixellation more than any thing else!...what happens when you change the font to something like Times New Roman???

No this is printed out with Word 2016 and then scanned as jpg with 600dpi.

...so you did not yet convert to PDF to print from yet???



PS--quick question....does the print driver have an option to put it in text/graphic mode instead of a photo type mode??? I have seen "sharpness" issues such as this resolved by making sure it is in a text/graphic mode instead of photo reproduction mode!

Re: Canon IR C5030i Gray veil around letters

I can convert it to pdf, there the error does exist anywhere. In case of print a test page with windows the shadows are also there.
I can put in the Printer settings as attachment.

I would test it by setting all of your "gradation" settings to off or normal...this is a very weird issue!...it doesn't look like a printer fault per se, but perhaps an issue between the software and how it interacts with the print driver!

[maximilian500]

Re: Canon IR C5030i Gray veil around letters

In the meantime I had full reset the complete machine and had set the gradation settings to off and on. But the error does still exist.
Can it be an toner error of black toner, that the toner is to old ?

Does this problem exist while printing from any other computers???
