As one of the first companies, we already had an Internet presence in 1999 with our broad selection of individually designable stamps and accessories. Today, we deliver our products to thousands of satisfied customers all over Europe. Selected solid components and state-of-the-art, high-resolution laser technology ensure that our stamps perform their work for a long time and with precise quality. This is why private customers like them as much as large companies or authorities that require large quantities. 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? An identity document is any document which may be used to verify aspects of a person’s personal identity. These can include:
If you can afford the extra expense its definitely also worth colour calibrating your monitor, this requires a colourometer such as a Spyder. These aren't particularly expensive, but are calibrated hardware equipment and so many times more expensive than a printed IT8 target (which you need whatever for this). You can use your non-barcoded stamps until Monday 31 July 2023. The original deadline was at the end of January, but after the death of Queen Elizabeth, Royal Mail introduced a six-month grace period to give people more time to use their old stamps.computer, 1 scanner, 1 stamp, 1 colour software, as long as they stay the same then all will be good on your computer. Shining light through paper (e.g. using light from above, a lamp, or a torch) is a useful way to view features such as watermarks, and also any damage to paper. Document scanners Secure identity documents are presented as proof of identity, nationality, status within the United Kingdom, and for employment or renting accommodation. The enhancement of scans through alteration of saturation and contrast is also a great help in identifying shades. Help for by-eye assessment then! Ken I have no problem with this idea, your stamp (certified) gives you a base colour (#ec2a65) scanned on your scanner 1, any other stamp scanned on that scanner you will be able to work with.
As said before in thread, the only way to standardise would be through sending actual stamps to others and that will never happen. I suppose a card of all the many GV Head shades is unavailable, as reference, for distribution? So my feeling on the best approach is simply colour calibrated scans to the ANSI standard then a visual comparison of the scans side-by-side on a decent monitor combined with experience. From that you either assign a shade (for a simple Green / Yellow Green example), or in the case of difficult issues - and Australia KGV 1d Heads are the ultimate in difficult shade issue - then an onscreen visual comparison of colour calibrated scans can give a good indication of when it might be worth (or more often not worth) sending a stamp off for a certificate. Hope you guys find it as useful as we have! We've been doing this a long time and have used everything from DSLR to 1200DPI scanners over the last 20ish years, and this one is the best thus far. Position the camera head around 4 inches above the subject and shoot. That's how we do it. If it's a big item, then stand it up a lot taller. The camera head also swivels 90 degrees so for wide or long shots, you can pivot it. While this is true it makes me think I have not explained the rationale behind this at all well If you have a certified stamp in-front of you and stamp of interest in-front of you then surely you would make a real-life comparison using a good natural north light? Taking a scan may help as well, but yes - colour calibration of your scanner isn't needed if the stamps are always going to be physically sitting together on your desk!! I'm looking to make colour calibrated scans work as well as possible for instances where real-life comparison is NOT possible. If your monitor is reasonably modern, with typical default colour settings, but uncalibrated colour-wise then all scans you view will be out by the same amount and you will still see the same shade differences between the calibrated scans you view. If its horribly out of calibration then this could start to affect the shade differences, but with the caveat that you have a half decent monitor and its settings haven't been totally screwed with then exact colour calibration should not be required (although always beneficial).
Self-inking stamps can provide thousands of impressions over many years.
Document verification is crucial in ensuring that the documents presented are both genuine and presented by the rightful holder. Swapping scanned images is not tenable or at least is too exhaustive in getting agreed calibration of monitors and colour swatches? What is frustrating is that showing scans here is never successful due to variations in monitors etc., so that some element of truth from the scanners perspective has to be given. The upshot of all this is: if you scan a KGV 1d rose pink stamp that has been expertised, sample a specific area and get (for example) #ec2a65, then the next time you're wondering if a particular stamp is rose pink, if you repeat the exercise using the same settings and get a close comparison (for example) #eb2e68, then it's probably worth your getting that stamp expertised too.
As for the calibration part if doing the above, there is no need for your system to be super calibrated 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. Thought it was worth putting together some information on colour calibration of scanners as the topic repeatedly comes up (directly or indirectly) on Stampboards and some good information is buried in threads. This isn't something I'm an expert on by any means - most of the info is based on what I've read on threads here. My experience is only using Canon LiDE scanners and their non-WIA Twain driver, some other scanner drivers may not have required options (particularly all-in-ones). I'm not assuming a colour calibrated monitor, but you'll want a reasonably decent monitor, older laptop screens can have pretty poor colour display range. Also my use of colour calibrated scans has been for convenience in IDing shades which are clearly distinguishable by eye. Colour calibration will be useful to some extent for all issues, but it is going to have limitations and I don't imagine anyone will be positively IDing Australia KGV Head 1d Red shades from scans - however well calibrated the scans So as not to be misunderstood I am saying that when one looks at identifiable (dated, UV assessed) GV Heads on scans there is a good correlation between shades after enhancement and the stamp shades presumed from the other data. Using the same scan with reference GV Heads one can relatively easily shade unknowns (again helped with any other data).
But price on request and the style of description suggests this is not going to be appropriate cost wise. In theory I assume you just replace the LEDs in a flatbed scanner with UV wavelength equivalents. Am sure that must be doable - ha ha ha - this from someone who has never managed to successfully get an LiDE scanner working again after popping the glass in my attempts to fix them! 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? The important bit being the last sentence. In practice calibration of the monitor is not essential and "calibration of the original" is what were are attempting to do - i.e. assign shades to the stamps. No matter what, if you have that base stamp you will always be able to compare it with a 2nd stamp anywhere anytime any computer.
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. A test would be if I sent an IT8 target, full instructions along with a few "test stamps" to someone who had some variant of modern LiDE scanner. They could then calibrate their scanner against the target, scan the stamps I'd sent, post the images and see if anyone could see differences! Or maybe not even an LiDE scanner - that's the settings I know, but I guess they are all pretty simple. The topic has risen intermittently over my few years here. I pose a few questions most have been answered above I am sure, but are getting mixed up. So for a single user (computer, scanner, software) assessing stamps against ´certified` (proofed) copies as standards on the same scan is no problem? 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.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?
Great Deal
