tell me about the copy size

The Input size, Output size, and Scale settings work together to determine the image capture area and the size of the resulting copy. The three are connected and changing one will automatically adjust the others following a defined order. You can select your size values from a list containing standard and custom predefined sizes. For the Input Size you can also choose to let the scanner detect the size automatically which is useful when you don't know the size offhand. Your scanner software always maintains an image's aspect ratio when input and output sizes differ.

Usually you would set the Input Size to that of the original, but you can also use small sizes to copy selected portions. With the Output size setting or Scale, you can blow up, shrink or make one-to-one copies of the original.

The Input, Output and Scale values are connected and changes to each automatically adjust the others.

The first time you set a size value, or just after you press reset:

• changing the Input size adjusts the Output size.
• changing the Output size adjusts the Scale
• changing the Scale adjusts the Output size.

You can use Auto width and length for the input size and a specified size for output. In such cases the Scale setting will be set to Auto until a first preview has detected the original's input size and thereby calculate the correct scale.

NOTE: Your scanner software will always retain an image's aspect ratio when the input size and output size differ.

Size values will also change when you adjust the paper frame through the Resize Paper Frame tool.

The Input size setting determines the scope of the scanner's image capture area.

You can use the variable Input size setting to capture selected portions of the original and thus make printed copies of specific image details. You also might want to print small strips of difficult areas for testing purposes before committing the whole copy to the printer.

The Output size setting refers to the printed result. For making a duplicate sized copy, you set both the Output size and the Input size to the size of the original, or set one of them to the size of the original and set scaling to 100%. For blowing up an original you set an output size that is larger than the input size, and the opposite for making a reduced copy. Blowing up and reduction can also be controlled through scaling.

Your scanner software covers most original and copy sizes with a wide range of predefined standard size options. But you may get an assignment in which a whole group of specially sized copies must be made, or you have a stable customer requiring a standard size of input material that is not as "standard" as the rest of the world's. In such cases you could save precious time by retaining the special size definitions in size presets that can be recalled when needed.

When you create a size preset, it becomes available both in the list of Input size presets and in the list of Output size presets because the list of preset sizes is shared by both options. This of course means that a new size preset can be created through both the Input Size and Output Size dialogs with absolutely equal results — a new size definition on the application's shared list for predefined sizes.
