As printer guy said he needs .cdr file for printing. I have coral but, don't know how to use coral draw. Please help me. This is very big problem to me right now. Anyone know easiest way to solve this problem.
There is zero conversion between Photoshop and CorelDraw. Essentially you would need to remake the file entirely using CorelDraw. There's nothing you can do to simply "convert" a file from Photoshop (.psd) to CorelDraw (.cdr).
If you merely place the Photoshop file into a CorelDraw document and then save/export as a PDF... it's pointless. You may as well deliver the Photoshop file. Using CorelDraw in this manner to generate a PDF does nothing but add a superfluous file wrapper before the PDF save/export, it doesn't "convert" anything.
If you have a file in Photoshop, you can merely save that file as a PDF. But there may be some reason a "printer guy" is specifically asking for a CorelDraw file... CorelDraw in itself is fairly uncommon in commercial printing circles, although not unheard of. And he, of course, may have suggested CorelDraw because you told him you have that application.
Beyond this, it is difficult to give any direction without understanding why a Photoshop file insufficient, why a PDF from Photoshop is insufficient, and why a CorelDraw file is actually necessary.
Essentially, without actually seeing the file in question and knowing how you are wanting it reproduced, there's no telling why the guy wants a CorelDraw file. Worse case scenario would be to save the Photoshop file as a .tiff ... which is more than suitable for commercial printing, provided the file's resolution is high enough (240ppi minimum).
Also, it's not uncommon for a printing provider to ask you for a different file format because they simply don't want to work on your project. Rather than merely telling you "no", they request a format they are aware you probably don't understand or have or can't create easily. That way you walk away feeling as if your file was incorrect rather than feeling like they refused your project. I can't say this is the the case for you. But it does happen.
This is not an answer. This is a long comment.
I do not want to be rude. You do not have a Corel Draw problem. You have a communication problem.
I. What is the project about?
Do you need a vector file? Is it for something like laser cutting or a vinyl sign?
Is it digital paint? Is it a logo? Is it a brochure?
Do you know the difference between a raster image or a vector image? Is it an image at all or the design of a magazine?
If it is a raster image, (which I doubt, because they would either simply flatten it or ask a simple format like tiff or even JPG) is it at a correct resolution?
II. Ask "the print guy"
He has already seen the project, he knows why he is asking that you should do it in a different program. If the project is not suitable to be done in Photoshop, there are specific reasons for it. You do not design a brochure on Ps, or a flyer, or a magazine.
If you do not know how to use a program, you can pay for someone to help you.
But asking on a forum (very good forum I should say) without information is the same problem you have with your print provider. Information. Clarify this with him and make specific steps to solve your problem.
