Building a frame :: I needed close to perfect alignment. The image extends to both sides of the card and the bottom. Here's a picture of my registration. First I figured out where to place my note cards on the pad. Then I lined up pieces of paper on either side. Every print after that was lined up in between the pieces of paper.
I haven't been to happy with my Gocco card racks. The cards don't stand straight up, they tilt at an angle. You have to be very careful. Any little breeze (even a walk by) will cause them to sway and bump into each other. Even if you use ever other slot, they can still bump each other.
Here's my new alternative ...
I tuck the corner under the bar to keep it from flipping up. Of course, I would tuck the corner with no ink. I couldn't get the camera to focus on just the white card. I really do need to get a better camera.
Ikea 's VINK CD rack for $2.99. Cheaper and more efficient than Riso's card racks. See the spacing ... no bump action aloud.
