Industry standard? For what? File formats or software?
There is no "industry standard" that I l know of that fits every industry.
The industry standards are TIFF, EPS, AI and PDF formated files.
To make those formats in my world.. corel draw is the king.
But each software has its place. I rarely use illy. I use Corel daily along with its many plugins that make it a world class software.
Locally some places demand MAC only files with a fee charged for non MAC files. So be it. That forces more than they admit to use non local shops who accept industry standard file formats rather than platform. I just printed 10,000 insert fliers out of area because of their unreasonable demands. (They demand MAC because they say it stops the nephew artists)
I Corel for
signs, I use Corel for CNC work and I use it for print ads lay outs.
Some say illy. But with more print shop asking for PDF files now it makes no difference who or what utility makes that PDF file.
