I have designed an infographic in an A4 size. in this I have kept a simple dark green colour sleek footer keeping in mind that it will be cut in trimming in printing. But now the client have asked to put up his Ph., email & website on that bottom sleek footer. But I am not sure how to send a sample to the client. He needs it for both web and print. Do I have to make two files in this case? one for web and another for print as his contact details will be coming at the bottom of the page but in printing it will be cut. Can anyone help pls???
The title of this question seems to have nothing to do with what you're asking.
Do you need to know the trim/bleed sizes? That's something you need to get from your printer.
If you're asking what to do, because your client needs this for both web and print use, then yes, you will definitely need two files.
Depending on what makes up most of your design (photos, text, graphics, etc.), you'll usually want to save the web version as a JPG or PNG. Use the Save For Web options (if using Adobe) and adjust your settings for the best image quality and lowest file size. Since this is an infographic, I would suggest saving as a PNG, assuming it is made up of mostly text and graphics (photographs are better as JPG).
For the print version, you will need to ask the printer what they require, as far as file type and dimensions are concerned. I just did a quick Google search and a standard bleed for the A4 size is 3mm with a safe area of 5mm inside the trim. You will most likely want to save it at 300 DPI and in CKYM color mode, but the file type depends on the printer. Usually PDF is a safe bet, but you never know. They may ask for something else.
If you're making the infographic for both web and print then yes you will need 2 files. That may be an export to a jpg and PDF, that depends on the type of graphic it is and what the printer wants. The web file will be RGB and the print file CMYK.
If the client has asked you to include his contact information on the footer, then you must redesign the infographic to make space for those details. But that discussion is between you and the client and whatever agreement you guys made when starting the project.
