Prepress Communication: Tips for Using Scanners

If you look closely, you will find that the scanner glass panel border is marked with a scale in both the horizontal and vertical directions. The scale is not very eye-catching and it is easily overlooked by us. However, these scales can greatly improve our scanning efficiency, allowing work that normally takes one hour to complete within twenty minutes.

For example, we have hundreds of photos on hand that need to be scanned. The size of each photo is the same. If you step by step and scan one by one, the workload will be enormous. Next, let's "slowly calculate subtotals." Let these scans become easy errands.

The first step: first determine the number of photos that can be scanned at one time based on the scanner's format. In general, five standard photographs can be placed on the A4 format scanner panel. If the system performance allows, we can fill the panel.

Step 2: Based on the scale of the panel border, the photos are arranged on the glass panel according to a certain rule. It is best to place the photo close to the panel frame when arranging, which can increase the accuracy of the positioning.

The third step: start the scanning program and preview the scanned object first. The scanner will display the photos placed on the panel in the preview frame. We can create a scan task based on the number of photos scanned at one time and select the scan area for each scan task (ie, the position of each photo on the panel).

Step 4: Click on the "Scan" button of the scanner to start the formal scan. Since it is a batch scan, no manual intervention is required. We only need to take out the scanned photos after the current scan task is completed, and place new photos according to the first placement. After the cover is closed, there is no need to preview and select the area. Just click on the "Scan" button and the scanner will automatically scan and archive the images according to the area set by the previous scan.

Tip: The scales on some models of scanner panels are simply a few page marks; or they are not on the panel at all, but are placed on the side (pictured). We can do some markings on our own to locate (of course, the scanner cannot be soiled). This homemade positioning line is sometimes more practical than the scale line. For example, the author uses a sticker with a low degree of adhesiveness to stick to the frame at intervals of the size of the object to be scanned at each batch scan, and tear it off after the scan is completed.

The fifth step: image processing. Because some photos are vertical and some are horizontal, some images may be reversed after the scan. We only need to use ACDSee's image rotation function to restore them to the correct position. Now, all we have to do is change the photos from time to time. Of course, the above method is applicable only if the scanned object size and layout are the same. If the size of the scanned objects is very different, we can only perform tedious operations step by step.
