I am trying to set up a Custom Page Size for use with tent cards to be printed for birthdays, anniversaries, etc. The base size is 7 inches wide by 10 inch high (17.8cm x 25.4 cm) with 0.25 inch margins (0.64cm). This will fold to a card that is about 7 inches by 5 inches. When I go into the page size specification and select Page Layout > Size, then scroll down to "More Paper Sizes" and when the Dialog box comes up, I scroll the Page Size selector to "Custom Size"and enter the width and height as 17.8 cm and 25.4 cm. I also set the default margins to 0.64 cm, Gutter at 0 cm and header and footer at 0 cm from the edge, all in Portrait mode. I allow it to default to "Whole document" and then click on OK. I also set a Page Border to use in aligning the components for the card, it will be removed prior to printing. When I go to verify that the custom size is in place, I find that for some reason, it has defaulted to "B5 (JIS) 18.2 cm by 25.4 cm", which is not the "Custom" size that I specified, although the margins 0f 0.64 cm do set properly. I do not seem to be able to figure out why this is happening. I would be very grateful if someone could shed some light on what I am doing wrong, or not doing, as the case maybe. Getting this right is very important to the production of these "greeting cards" as positioning is everything. Thanks in advance for your help.
