![]() ![]() I sent my scanner back to Plustek but it came back with the same problem as when I sent it Sometimes the scan starts load and fast but then the infra red scan runs slowly in this case the ISRD will not work, the image will be scratched and grainy. Take notice of the noise of the scanner when scanning 3600 or 7200 dpi if it starts quietly the scan will be dark and take 5 minutes with 3600 and 15 mins with 7200dpi and if it starts loudly the scan will always take about 1 minute. ![]() I can confirm that the red frame needs to tight around the image, otherwise the bright edges have an impact on the overall brightness, however this may not be the reason for the dark slides. When you contact Plustek I would assume a few sample scans should be enough to show your issue. This enhances color stability and makes sure the scanner uses a controlled and defined color space. This depends largely on the individual device.Īlso as all optical devices scanners are subject to external influences.īoth temperature and humidity can influence how a device sees color values.Īn individual IT8 calibration will measure the true range of colors for an individual device. So an image scanned again on the same device after a few years might look a little different.This might or might not be visible.Īlso individual devices might show variations in color representation if compared. Of cause devices change over time and the way certain colors are seen might change. This means that the minimum and maximum values of the colors will always be met. This means the shipped profile tends to be smaller than the scanner's potential color space. Generally the the shipped profile is generated in a way that it will fit all production models. So far we never had any significant variations. In case the production is altered we also get a new testing device. ![]()
