Calling all designers using Adobe庐 InDesign! If you鈥檙e looking for best practice tips and optimization techniques to maximize your design output, our three-part XMPie Designer Blog Series is just the ticket.

In this series we鈥檒l explore a variety of ways for designers to improve performance and boost output results, ranging from image resolution and cropping to transparency effects and proper use of layers. All of XMPie鈥檚 products are tightly integrated with Adobe InDesign Creative software, allowing designers to work with familiar best-in-class tools.

Part 1: Optimizing Images For Your Layout

Designers use images of all shapes and sizes to enhance a wide variety of personalized print applications. When using images it鈥檚 important to understand where the images will be used and what size and resolution are required. Image size and resolution is always important but its impact is multiplied by many folds when producing a variable data job that may use the image repeatedly. Let鈥檚 take a look at the example below.

For this catalog sample, the layout requires many small images to visually display the product lineup. We鈥檝e duplicated the items to showcase the difference between 聽resizing images and resampling them 鈥 though they look identical, they鈥檙e actually quite different.

Let鈥檚 look closer at the strawberries. The strawberry image on the left is an image that was resized in Adobe InDesign and the strawberry on the right is an image that was resized (actually resampled, which means the number of pixels in the image changed) in Adobe Photoshop.

What is the difference between the images? The answer is in the 鈥楲inks鈥 palette (Windows > Links). Within this palette, look for the effective PPI (or resolution) and file size for each strawberry. You鈥檒l notice significant differences between both strawberries 鈥 The strawberry on the left has an effective PPI of 3,333 with a file size of 5.5 MB, while the one on the right has an effective PPI of 600 with a file size of 255.6 KB.

High resolution images that are resized directly within InDesign (like the strawberry on the left), still retain all the pixels of the original image, which can result in a 鈥渢oo high鈥 effective resolution. InDesign will resize images, but it will not resample, which means it will not change the number of pixels in the image. This can cause, not only a slower production time and larger output file size, but a bloated document that is heavier to save, pack and transfer as well. 聽Resizing an image inside InDesign will suffice in cases where the size change is minor or if you need the image鈥檚 resolution to be higher than the 鈥楢ctual PPI鈥 and you are comfortable with the 鈥楨ffective PPI鈥 that you see.

However if that鈥檚 not an option instead of resizing the image directly in InDesign, bring the image into Photoshop and resize it to meet the dimensions you are specifically looking for in your layout (The 鈥業mage Size鈥 dialog box in Photoshop has the 鈥楻esample鈥 option enabled by default). From there the image can be placed back into InDesign, bringing the effective PPI into a range that won鈥檛 hinder productivity. This will help maximize performance, reduce the file size and give you a faster RIP time.
