How to convert between RGB and CMYK in Photoshop
Make sure your image is flattened. If your image is not flattened, place the mouse pointer over a layer then right-click and select "Flatten Image". Go to the Edit menu, and click on "Convert to profile". Use the dropdown to select your desired color mode, and select the second option of "Destination Space profile": "Working CMYK - U.S, web coated (SWOP)v2". Click on OK.
How to resize an image in Photoshop
Click on the "Image menu" and select "Image size". You will now see adjustable cells for width, height, and resolution.
This image is 4000 Pixels in width and 6000 pixels in height and the resolution is 300 PPI(Pixels Per Inch). For printing, we should keep the resolution of the image 300 PPI. Enable "Constrain aspect ratio". The original width proportion to height is preserved so the image doesn't look stretched or squeezed.
We would like to make the size of the image 8000 pixels "Width". Now type 8000 on the width cell. So enabling "Constrain aspect ratio" we can see the "Height" is 12000 pixels of the image.
Ensure the check mark of "Resample" and Resample is "Preserve Details(enlargement) ". Reduce noise is 100%.Click on "OK".
Now we can print the image.
