I am having kittens here! I have my own little graphics business that I am trying to build up. I have started selling certain designs, and the design in question is for a wedding invitation. The client wants 50. The size of the invitation is 130x130mm. I am printing on silk card which is always fine and I get really good results, but this time the client wants a double sided print. I am using a Canon pixma mg5550. I have worked out that I can get two invitations per a4 sheet. So after printing two of the invitations on a sheet, I am feeding it back through the printed to print the back of them. I am using crop marks to cut them down to size. Sadly, when printing the back of the invitations on the same sheets, they are not lining up and I have been here for hours messing with it. I have made sure that the invitations in Illustrator are dead centre in the middle of the A4 page but it still isn't working. Can anyone help please???????
