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

Sounds like a font issue.

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.

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.

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.

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}
\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.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.

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.
