how do i save a file as PDF/X1a 2001 for printing??

My printer requires PDF/X1a.

How do I convert my PDF into a PDF/X1a? 

This is the only reason I have Adobe.

Hi

if the printer asks you to delete ICC colour profiles, that's maybe because their RIP (which makes the plates) doesn't like embedded ICC profiles. This is not an entirely unusual request.

In colourmanagement workflow, we generally like ICC profiles to be embedded in files, because that tells us (in the case of CMYK) how that CMYK was made, i.e. what ink recipes were used. Those ink recipes and inklimits are specific to press and paper types, any old CMYK just won't do.

more here: https://www.colourmanagement.net/advice/about-icc-colour-profiles/

and: https://www.colourmanagement.net/advice/prepress/

In this case, because it's been requested, it's OK to save your images without profiles embedded, BUT - and this is IMPORTANT - when you made the CMYK conversion from RGB originals (or when you set up your blank document) you MUST use the right CMYK ICC profile. There are standards for this such as ISO 12647 and in the US GRACoL, but, ideally, the printer themselves would tell you what they want.  CMYK made for a different press type or paper type isn't going to print nearly as well as when its 'separated*' correctly 

*separated means making CMYK fromk RGB, the ink values are calculated, thoise values are needed to reproduce (as well as possible) the RGB original colours - so its super important to get the CMYK ICC prfile used in this conversion right. Please DO NOT just use Photoshop's default of SWOP coated unless you are specifically told to, even for the USA that’s out of date now. And its entirely irrelevant for European print. 

I hope this helps

if so, please "like" my reply and if you're OK now, please mark it as "correct", so that others who have similar issues can see the solution

By the way, unless your printer has specifically asked for PDF/X-1, the recommended format is PDF/X-4.

»Printer also ask me to delete ICC COLORS profiles...«

What did they ask for exactly?

PDF/X have to have a defined OutputIntent, so the request seems unclear. 

Can you provide the file? 

What is the Color Space of the original image and what is the Target Space?
