Hi All,

Fix the 300 dpi for low les image without affected in pixels of the images, if it is possible? Do you have automated script here. Any ideas for these, please share with us.

 

Regards,

James

Thanks stephen. I need change the resolution more number of the images, so need the automated script.


The effective print size will always shrink if you increase the PPI without resampling, no way around it.

 

If you wish to maintain the original print size and increase the resolution, then you have to resample/interpolate – generate new pixels (with all the pros/cons that come along with resampling).

 

You can record into an action and batch as long as you use save and a format that retains resolution metadata.

 

What file format/s are you changing?

You can elect to change the resolution via Image > Image Size with resample unchecked, which will make the canvas size bigger or smaller without adding/removing new pixels.

 

If you changed a 72ppi file with resample off to 288ppi, then the canvas would be 1/4 the size.

 

Or you can tick the resample box and keep the canvas size as is (or change it) and add or remove pixels by changing the resolution.

 

It's one or the other.
