Why the designer use the limited software for graphics?

LIMITED!!!!

OH WOW!!!!

it is your imagination which is limited my freind.

Graphic Design Software is Vast!!! Huge!! Unlimited!!! It is not about how many software you have! It is about what a DESIGNER CAN DO IN ALL OF THESE SOFTWARES 

whether the designer was in Graphics, Motion Graphics, VideoGames Developement, TV Ads, Printed, and even in movies

I think the best response could be: a designer actually don´t use limited software for graphics.

Anyway, As a professional i allways consider use the same software as my print-Web Hosting-And-Whatever providers.

A good graphic designer should not limit what software want to use because it makes your world revolved on you own chair.. 

My Friend, now days it is  more specific . theres is Prining Graphic Designer, Web Graphic Designer, Flexo Graphic Designer, packaging Designer, Branding Designer, Logo Designer & More..

the best designer who has ability and knowledge about how to get what you want easily and quickly to match deadtime so if you will design a logo or another creative idea you have to use program which help you in your work without Dispersion of your  thinking.

The person who limited himself with limited softwares, actually he is not a graphic designer. 

The right tool for the job EVERY time. A good designer can adapt and learn on their feet. The toolkit should cover their clients needs. Graphic design is taent and imagination, a tool is only the means of converting that into a physical file\\image etc that can be displayed.

There are more tolos than I can list, again the tool to turn the designers talent into the client requirement is the right tool.

In corporate companies they use limited software because of the project dealines and also they can't experiment the new softwares.

But If the designer comes out from the office then there won't be any dead lines and he can experiment on all kind of designing softwares.

And I am pretty sure that, there is no limit for designing softwares or designs.

because some people not want to use other software they know only some software

In Graphic design , every day and every moment you have  something to know, 

You can not limit the choice but the professional software is the family Adobe and Autodesk at the base. There are also others when it talks about the video games, that consists the graphic power.

so it depends on the exact specialty in the graph field.

Adobe, Provides All Designing  Relative  Software. Adobe Is Best , Very Best ....
