Chose "Cards and Games".
Then "Game Cards".
Then "Personalized Poker Custom Cards (Blank Cards) Playing Cards" - you want 63,5x89mm.
Then
- Card quality. You have to choose (i used Standard)
Standard 300gsm casino quality cardstock aqueous coated (smooth finish)
Premium 310gsm casino quality cardstock plastic coated (linen finish), origin of material from France
Superior 100% plastic PVC cards and thickness of 0.325mm, origin of material from USA
- Size of deck - depending on the number of cards you need.
- Boxes - Shrink wrap as usual.
Then "Personalize it".
Choose what you want to put on card fronts:
Image & Text
Same for all fronts*
Different for all fronts
Color Background & Text
Same message for all fronts*
Different message for all fronts
You then upload your images (min 300dpi) and drag them.
A warning LOW RESOLUTION will be shown for MSE files, but i printed it anyway and it was ok.
The program crops the black border, sizing the rest of the image. I like it, but people seems not to agree.
Dom seems to know how to avoid that.
Kjeld' solution : Also, it's relatively easy to set up a template to extend the black border. Basically, you want a base card image that's 750 x 1050, including the black border. Then extend the image size to 822 x 1122, and fill the new space completely with black. It will look weird -- with a really thick black border -- but when you submit the final 822 x 1122 image (as a .png preferably) to Printer Studio it will print out very nicely.
Kjeld about colours : Also, in my experience the colors tend to come out on the darker side, so you might try brightening the image 10-20% before submitting it.
