Hello I'm using LR 6 (which doesn't get much love in these forums). I will creat a Preset for export once I learn the answer to the following question: I'm trying to export to my harddrive, then upload to Costco, to print 12 x 18 and 12 x 12. This is my EXPORT window screenshot:This is what Costco says I need to do:The driver for Costco's Epson printers is optimized for 300ppi images. Resize your images to 300ppi at one of the supported print sizes. For example, a 16x20 print should be sized to 4800x6000 pixels at 300ppi. Using other dimensions will result in image resizing by the printer driver. NOTE: I PLAN TO PRINT 12x18 and 12x12Thanks for any help you can provide.

Hello

I'm using LR 6 (which doesn't get much love in these forums). I will creat a Preset for export once I learn the answer to the following question: I'm trying to export to my harddrive, then upload to Costco, to print 12 x 18 and 12 x 12. This is my EXPORT window screenshot:

This is what Costco says I need to do:

The driver for Costco's Epson printers is optimized for 300ppi images. Resize your images to 300ppi at one of the supported print sizes. For example, a 16x20 print should be sized to 4800x6000 pixels at 300ppi. Using other dimensions will result in image resizing by the printer driver.

NOTE: I PLAN TO PRINT 12x18 and 12x12

Thanks for any help you can provide.

Correct answer 99jon

For 18 x 12 inches at 300ppi you would need a long edge of 5400 px e.g. 5400 x 3600

This assumes the original aspect ratio is 3:2

If the original has smaller dimensions some re-sampling will be necessary.
