PNG files must be RGB, as the format inherently doesn't support CMYK; it's designed for screens and web use, so if you're printing, you need to convert to a CMYK-compatible format like JPEG, TIFF, or PDF, usually by exporting from your design software (like Photoshop or Illustrator) and asking your printer for the specific profile needed.
png file does not support CMYK and will always be converted to RGB. A color mode is a term used to explain how your program or device is interpreting the color.
PNG files don't support CMYK, that's why they switch back to RGB, export a JPEG or a PDF. If you need transparent background, then export as TIFF.
JPEG. The JPEG (Joint Photographic Experts Group) primarily supports the RGB color mode and is arguably the best-known file format for photos and other digital images. While creating a JPEG using the CMYK mode is possible, many applications reject such files.
As mentioned above, . png files can only be saved with RGB (Red, Green, Blue) colour profile which is basically for on screen images only.
Generally you want to setup and save your file at 300 DPI and "save as" or "export as" . png as high quality instead of a quick export. This should maintain the size and quality of the file.
In particular, PNG supports truecolor images. We know of no widely used image format that losslessly compresses truecolor images as effectively as PNG does.
Instead of recognizing red, green and blue (RGB) values often used on computer screens, high-end digital printers use a CMYK color wheel consisting of cyan, magenta, yellow and key (black). In both processes, colors combine to print dark colors that may appear as black ink.

PNG supports two kinds of transparency with grayscale and RGB images.
The biggest difference between the RGB and CMYK color mixing modes are what designs they're used for. RGB color mixing is the primary color mode for digital designs (like web, TV or phone files) while the CMYK mode is used for printed designs (like T-shirts, flyers or business cards).
The png file format does not support CMYK. A CMYK png is not possible.
Yes. PNG files maintain sharp edges and fine details better than JPG, so PNG is perfect for printing text, diagrams, and logos.
PNG files don't support cmyk.
To convert the input PNG to the desired CMYK channel, activate the corresponding checkbox in the options. Additionally, you can obtain a monochrome version of each CMYK channel using the "Create a Monochrome CMYK" option.
The RGB is inevitably much brighter and punchier on screen, whereas the CMYK pallet looks dull on screen. This is how we would expect CMYK to look as it's not formulated to look good on screen. When it comes to printing, however, that's CMYK's time to shine and the 'dull' colours don't look so dull anymore.
PNG is short for Portable Network Graphic, a type of raster image file. It's particularly popular file type with web designers because it can handle graphics with transparent or semi-transparent backgrounds.
sRGB is sufficient for most uses and has a smaller range of colors, mainly noticeable in blues and greens. Adobe RGB has a wider range of these colors, making it better for high-quality prints and RAW photography, where you can choose the color space later.
png file is saved at a very small size—say, 1 inch wide—and you try to blow it up to 10 inches wide, it will look blurry. With these flat files, the computer can't create additional pixels when they're scaled up. So, the pixels themselves just blow up and look blurry. To account for this, I always save .
This one is for images that use the additive color model. This is not surprising when you remember that PNG stands for Portable Network Graphic, i.e., intended for display on monitors. While CMYK is a subtractive model designed for printing.
Why is RGB not ideal for Printing & Packaging? In most printing processes, RGB color space is usually converted to CMYK before creating the artwork. Essentially, any colors produced with RGB on the digital space will not create the same output on the physical print.
Disadvantages of CMYK
So, for printing onto paper, the CMYK printing process is used.
Right-click on each RGB image and select Edit With > Adobe Photoshop to open the image in Photoshop. In Photoshop, convert the image to CMYK by going to Image > Mode > CMYK Color and save the changes.
PNG images are commonly used in files, however, PNG files are not the best to use in large format printing because they only support RGB color profiles and when it's printed in CMYK color profile it can yield some unexpected results.
The default color for transparent regions is black, the default color for semi-transparent regions is red, and the default color for opaque regions is white. Additionally, for semi-transparent pixels, there is an option to display the actual degree of transparency.
