General ⇒ Why pdf generated from(TexStudio) LaTeX are not dark and blur

[coep05]

Dear All,

I am using LaTeX for writing articles. When I take Print out of these article, the Print comes out blur i.e. texts are not Dark; whereas when I take print from doc or pdf generated from doc, I am getting normal print.

I am using "pdflatex" option in "Default compiler". I tried using different printers.

I searched on internet, people have got this issue but that was before 2010, and there solution was given to use "pdflatex".

So, if anyone had similar issues, please give the solution.


Thank You.

Can you post such a PDF here as attachment? The "Attachments" link is below the text edit field, when writing a post.

Sounds like a font issue.

Dear Sir,
Actually in PC the pdf looks good, but after taking the print(B&W) of same pdf, I am not getting the print in dark black color and the text and some symbols not visible clearly.

I have attached the PDF and the image of print taken of that pdf for your reference.

The PDF is fine and can be printed on my OKI laser printer without any problems. So I can give only some general notes:

Computer Modern is a high quality font. It was made for professional printing engines. So please do use a printer resolution of at least 600dpi and deactivate toner/ink save mode.

For low resolutions or toner/ink save mode other fonts are better, e.g. Charter. But in this case you should also use thicker lines in graphics.

And some color printers use color ink for black, if the page/document contains colors and real black only for black and white pages/document.

I tried print by changing the dpi to 600, it gave bit dark print (better than earlier). But still not that clear.

And to add, 'Computer Modern font' which Package I need to add in the document?

And regarding adding 'xcharter' package: I am using a Template of Journal, so if I use this Package, whether it will affect/change the font style of that template?

Thank You.

Quick question: as you use the journal template, do you make that document for sending it to the journal? Then they would do the printing and it should be fine, since the PDF looks good and Ijon's test print was ok too. They print stuff with their template and the fonts used in that template.

If it's just for yourself and your printer, right, you may want to fix it yourself.

How about this, at the beginning of the document:

Code: Select all

\PassOptionsToPackage{cmyk}{xcolor}

(And \usepackage{xcolor} in the preamble if it's not loaded already)

That way, using the cmyk color model instead of rgb, may have an effect. It's worth a try.

Plus, perhaps funny idea but who knows: \color{black} after \begin{document} to enforce true black.

Yes Stefan,

The Printing issue is for myself. For the Journal, we need to send the pdf and at the end the source files. They will take care of the prints of their Journal .
I am concern about print for myself.

I tried the \usepackage[cmyk]{xcolor}
\PassOptionsToPackage{cmyk}{xcolor}

at the usepackage section. But what does these packages do? After printing with these commands also there isn't much change.

Thank You.
