About Image Sizes

Pre-sizing Images

Images do not require to be pre-sized to the requested print size, however images which are not proportional to the requested print size ratio, will crop the image around the centre axis to suit the ratio of the requested print size.

8x10 crop
Ie. If you have an image with a ratio of 2:3 (e.g. full frame 135size) and request an 8x10, the result will be an 8x10 borderless print with 1” cropped from both left and right hand sides.(This " Fill In" crop effect will be shown in the RPX online ordering program in the Preview Screen.)

"Fit In" If you wish to print the whole image . it is necessary to make a canvas proportional to the requested print size. In the above case the canvas would be 8x10 and the image would be re-sized as approximately 7x10 within the 8x10 print area as shown.

If you wish to print an exact size which is not available, re-canvas the image to next nearest available print size. (eg you want a 7x9" recanvas to 8x10")
There is no facility within the program to achieve this. More information on this below.

* The final image should allow at least 2mm bleed all round for over sizing. (Please see Quick Overview for more details on Bleed)

FILL IN and FIT IN in versions and higher
In the "PREVIEW" screen of versions and higher allows for this with the use of the "Fill in" and "Fit in" buttons located on the right hand side "Effects Panel" Simply select the image and click the "Fit in" button. The image will be resized to best fit within the print size you have chosen to achieve the above in one easy step. This can also be acheived in the dialog box when clicking the"Set Default Print Size" button within the windows version.

To optimize images for the best quality vs upload speed for the Digital Works Online Ordering program set the image to 200dpi(ppi) at the required print size

How to resize Images

In these experiments we assume some knowledge of Adobe Photoshop.

  1. With the image already open in Photoshop;
  2. Check the image size, <Image> <Image Size> is at least 200dpi.
  3. Make a new canvas to the available print size you require at the same dpi as the image. <File> <New>
  4. With the Pointer Tool selected Click on the opened image and with the shift key held down, drag&drop your image onto the new canvas.
  5. Holding down the shift key and using the corner grab handles of the transform tool selection box <Edit> <Transform> <Scale> shrink or resize the image to fit the new canvas


With the image already open in Photoshop;

  1. In the image size dialog box, with the “Proportional” check box selection on, change the Image Size to 200dpi, at the dimension you wish to have the final image <Image> <Image Size>
  2. Change the canvas to the requested print size. <Image> <Canvas Size> change the height and/or width to the requested print size dimension.

NOTE: If you have already opened this image in our online ordering software, in the ‘ADD IMAGES’ screen you will need to ‘right click’ on that image and choose ‘Delete’ from the popup menu then ADD the image again for the changes to take effect.
