When I first started scanning stamps using a flatbed LiDE scanner the driver colour settings defaulting to something called Recommended. I guess a good setting for scanning photographs but on the monitors I used it made scans of stamps appear over exposed with vivid colours and "overly white" whites.

In fact the scanning of the GV heads and adjustment is useful however matted the stamp as it is the coloured elements that ´light up`. Swapping scanned images is not tenable or at least is too exhaustive in getting agreed calibration of monitors and colour swatches? If your hardware has been calibrated and you tell me those results, and my hardware has also been calibrated and I examine a stamp and get very close results, then it would be worth while me getting my stamp expertised. Without both systems being calibrated, any close match is much less meaningful. Pink is a wide group of shades. Beech says, "They vary in daylight appearance from orange pink to lilac pink, with intermediate shades of rose pink, pink and lilac pink. There are dull, bright, deep and pale shades.........". I hope your system can cope with that.

An identity document is any document which may be used to verify aspects of a person’s personal identity. These can include: Nailing a colour to a number via software is almost impossible due to inaccuracies of where one has selected and internal colour components in stamps as well as calibration effects? Barcoded stamps featuring both King Charles and Queen Elizabeth are both currently in circulation and will both will remain valid after 31 July. There is currently no date when barcoded stamps featuring the Queen will become invalid. Can I donate my old stamps?

Once you have your target you scan it with all scanner colour correction disabled, save it as something lossless ( so not JPEG) and this gives you an image with the raw information from your scanner which can be compared against the published "true readings" for your target. Free software (I used something called "LProf open source ICC profiler") is then used to calculate the required colour adjustments which when applied to your scan would give the same colour figures as the reference figures. Iain if you have a certified stamp IE a pink stamp and you think you have another scan both stamps at the same time on any scanner with any monitor with any scanner setting on any windows program, if they look the same when all is done you have another pink again as I said before if the scanner or any of the other bit dies the 2nd stamp is still a pink just as the 1st. So....why calibrate the scanner if the item you're scanning is not perfect to begin with and the colours depicted on the monitor vary between users? As for the calibration part if doing the above, there is no need for your system to be super calibratedThese are useful tools for identifying whether documents are made from secure paper or UV safeguards are genuine. Transmitted light No, I'm not, you've definitely totally missed the point of this entire post. It was about colour calibrating your scanner. Going beyond that I've made reference to then using colour calibrated scans of multiple stamps to make visual judgements. Similar (although not the same) visual judgements you make by eye with multiple stamps infront of you in real life. But if that scanner dies and then you will have to do a rescan of the first item the (certified) one, and you base any future stamp on that. Note: Non-barcoded Christmas themed and commemorative stamps will still be valid for postage past the deadline and cannot be swapped. What will happen if I try to use an old stamp past the deadline?
