Question re print DPI

[tracey.]

hello
I am trying to put together some booklets, using vistaprint as ive been happy with price and quality of flyers & leaflets Ive had from them. Ive created the booklets pages in Affinity Designer - A5 300 DPI, all pages created the same spec and uploaded as PDF as advised on vistaprint site.

The PDF are uploaded in one go - so all 12 pages are one document but my issue is that before proceeding to the purchase page theres a message saying some of the pages arent a high emough resoultion and they need to be at least 300dpi... all pages were created at that so I have no idea how to move forward .

Ive tried creating leaflets, not to orderm just to see which pdf comes up as too low but it doesnt have the message there (even though I also creted one at 152dpi just to see if the 'low res; message came up and it didnt) so it seems they dont warn about low res on leaflets but they do on booklets

If you are new to the pre-print world, it looks like a minefield of gotchas! My guess is that you cropped something or an image prior to printing to pdf. That is a usual novice mistake! I have never dealt with Vistaprint and this is the first time I have heard of Affinity Designer as the whole industry uses Adobe and lays out in InDesign (which flags up problems nicely for the times one goofs!)

Of course, you may have included an element (e.g., a picture or design element) that is below 300 dpi. The trick is to render everything to a very high dpi number and then you will not get this problem. If 600dpi has an element that is 550dpi that's not a problem. At 300, 299 becomes a problem!

My 30 cents worth would be for you to get an older Adobe CS3 on eBay including InDesign - you can get copies for almost nothing, under £50. (I got CS3 Master Edition for free in 2008, after doing some work for Adobe and it still covers all my layout needs.) You can forget Premier for video. It was the bee's knees maybe ten years ago, but DaVinci Resolve (it's free!) for professional use is rapidly gaining ground and if it's good enough for Roger Deakins then its good enough for everyone else! We also use Vegas for ease of use.

Thanks, yes Ive included elements which are pre purchased images, I will give your advice a go.

These are unlikely to be hi-res. Use your image editor to check the resolution of these images.

The iossue probably isn't around the resolution, its about the size.

If you blow a 2cm x 2cm image up to 100x100ck, despite the 300dpi resolution, you will loose quality.
