The most common cause of image pixelation is the resizing of pictures. When you resize a small photo to its larger version without doing any technical work on its resolution, the bitmaps appear on the screen.
Human or camera errors can also cause your images to appear with pixelation or blur. To embed a link, place the image in your file as you normally would, then find the image in your links menu.
An icon will appear beside the image letting you know the image is embedded. This panel is also accessible from interactive panels such as Animations, Buttons, and Forms by clicking the Preview Spread button at the lower right corner of those panels. To exit preview mode, click Turn off Preview in the extension or on the experiment details page. Then select the image. The Info panel will show you the Actual ppi and Effective ppi.
Effective ppi refers to the image at your chosen scale. See how the effective resolution is what really matters? What you really care about is how it looks when printed or exported to PDF for digital documents. Just because it looks good on screen does not mean it will print that way—always get an accurate proof! If your image is a vector image, it has no set resolution, and is therefore scalable to any size! Placed PDFs will also not show any PPI information as these are containers for raster images, vector images, text, and other objects.
Now when you have preflighting turned on and your custom preflight profile selected, images that fall below your minimum desired resolution will be detected and flagged as errors. See also: Customizing a Preflight Profile. As for the all-important question of what is the right resolution for your images, the answer is that it depends—talk to your print vendor for the best option. However, you will notice that the example above is set to ppi, which is high enough for most printers.
Requirements vary for newspaper, magazine, and high-end jobs, but typically most people request ppi. It also depends on the content of the image. The output method is important too. Digital printing is a bit more forgiving than lithographic printing, so you could risk going below for a digital print. When you have your display performance set to High Quality for all images, you can experience lag in InDesign, sometimes a serious lag.
For a complex vector-heavy image like a CAD drawing set to High Quality all the time, you will almost certainly experience InDesign lagging, which can be frustrating! If this is the case, consider only using High Quality for rough layout purposes, then set it back to Typical when you are happy with the image positioning.
Another option for changing image display settings is Object Level Display Performance, which allows you to control the onscreen appearance of images on an individual basis. For example, you may need a certain logo to always display at High Quality, but you might not care about the other images in the layout. So, you could go to Preferences, edit the Fast setting, and drag the Vector slider all the way to the right. Now just that logo will display in High Quality.
Question: Why does ID often Place my images at a much smaller size than the image itself? Usually this happens to me when I am working on a document that has the ruler measurements set in pixels for ebook design. When I Place the image as an inline image within an existing text frame , it is almost always Placed as a much smaller image.
For example, pixels wide still proportional though. Usually it only does this for 72 ppi images, though. My basic text frame is about pixels wide in the document I was just working on. The menu at the top says its width is 48 and height is The issue only happens with nonppi images actually, and based on the math, InDesign is doing something to the dimensions of the image based on the ratio of That ratio is 0.
But WHY? And is there an option somewhere for me to tell ID to stop trying to decide what I want and just place the image exactly the way it exists?
If the image is set to be at ppi, ID place the image at the dimensions you need to print it at dpi. Thanks for the article, this had frustrated me for ages! Ended up tracing all the images in InDesign to insert them as. I was on deadline to finish my media project but man God Bless you, everything has worked on two clicks. Thank you. Hi this article was helpful to see how you can change the display. I am still having difficulties on my PC.
I opened my logo that I created in photoshop and put it into the library cc and opened it up in Indesign. When doing so, I just get the gray box, after reading this I am finally able to get it to show up but it is still extremely grainy.
The concern is, is that if I open it up on a friends mac computer and do the exact same steps it is crystal clear. I need to be able to work on my computer but I need the image to be clear. Can someone please help me understand why mine is not, and help me fix this? Thank you so much, Michaela Gensler.
Macs often have retina displays—and InDesign can see that—so it increases the display performance accordingly. Need training at your office?
