Image Resolution ( DPI )

Images to be printed should have 300 dpi (dots per inch) or more for a better quality. But you may be confused or wondering why you got a 72 dpi image from Offline Presence.

 

Why 72dpi?

The reason why we get a 72dpi is due to a software constraint in Offline Presence. By default the software outputs this setting for the designs you download.

 

Is 72 DPI good enough for print? 

Yes. In fact it has the same quality as a 300 dpi image, the only difference is in the dimensions and resolution.

For instance, let's say we are working on a business card which dimension is 3.75 x 2.25 inches(with bleeds), with a of 300 dpi - making its pixel dimensions to 1125 x 675 pixels. 

After downloading the image from Offline Presence and opening it with Gimp or Photoshop we will notice that we got a 72 dpi resolution and image dimensions of 15.625 x 9.375 inches. Still the good thing is that we still got the same pixel dimensions - 1125 x 657 pixels.

 

Image setting (Business cards)

Ideal image setting: 3.75 x 2.25 inches in 300 dpi, 1125 x 657 pixels

Offline Presence setting:  15.625 x 9.375 inches in 72 dpi, 1125 x 657 pixels

As you may notice, only the DPI and document sizes vary but the pixel dimensions remain the same. This means technically that the quality has not changed.

Can the image be set to 300 dpi?

Yes. You can change the resolution to 300 dpi from 72 dpi but you also have to change the document size. You have 2 options, first is to ask the printers to do it for you and second is to do it yourself.

 

1. Let the printers do it for you

You can ask your printers to edit your image's settings. Let them know about the image issue and that we only have to change the resolution to 300 dpi and lower the document size to the right print size. 

 

2. Do it yourself 

A. Using Photoshop

For instance we want to set our business card from 72 dpi to 300 dpi

1. Open the image in Photoshop, click File and then click Open to browse the image you want to open.

2. Once the image is opened. Click on Image button on the tops left and then click Image Size

 

3. A dialog appears. Change the resolution to 300 dpi  and the document size width to 3.75 inches (the height will automatically change to 2.25 inches since by default proportions are constrained).

4. Click OK to update image. 

5. Click File and then click Save or press Ctrl + S to save and overwrite the image.

B. Using Gimp

For instance we want to set our business card from 72 dpi to 300 dpi

1. Open image in Gimp, click on File and then click Open to browse the image you want to open.

5. Click on File and then click Export As...

6. A dialog box appears. Type in the name if you wish to change it.
