You seem to be reacting and freaking out any time somebody points out things you don't agree with or have not thought of. You might want to consider sleeping on it before you post any answers in the future.pierreLOL!!!! Now you're taking it to personal attacks. Again, typical. This is why I don't bother with this board. Your statements are not factual, they are unqualified statements that are assumptions about the physical aspects, not facts. You said: "something to remember here is that the polarized glass of the LCD display will stop 50% of the light from coming through" Which LCD panel are you talking about? Which polarizing film? Do you think 50% is a factual number associated with the amount of light passing through the LCD, the amount of actual UV, etc etc.... maybe its 25% maybe its 75%, maybe its 50%, but you clearly just threw that number out there without doing research or 'qualifying' the statement so it could be considered factual. Again, it isn't really a hurdle to overcome any more than typical hurdles in exposure based on the tolerances and variables required. Yes, there is a piece of polarizing film before the LCD and after the LCD, it is how it works, but simply saying it "will stop 50% of the light" is not a factual statement, it is a generalization that could be way off when you actually qualify it. So do you mean 50% of the UV light at the 405nm wavelength will be stopped through a "brand/manufacturer specific" panel, which needs to be specified which one to be qualified, and of this light at a given moment in time from what is reaching the panel to what it coming through the panel, do you know the ratio of how much light is coming through the "blocked" areas of the stencil, and do you know the comparison to this vs. the amount of light going through a piece of film and what makes it through the blocked areas? For your statements to be factual you would need to qualify it with all of those actual physical system connections. Otherwise it is as I stated before, just an assumption you are making. Do you understand the ratio between how much UV is passing and how much is being blocked? The contrast ratio for the LCD might actually be greater than that of "specific film" with "specific ink/rip/density" or compared to DTS with the wax/ink, or with DLP. DLP probably has the highest contrast ratio, since there is no "blocking" stencil, it is only exposing direct UV Laser or LED light onto the emulsion. LCD might have the second highest contrast ratio because the "dark" areas might be blocking more light compared to what is passing, comparing with what film or DTS is blocking and allowing to pass. You might want to qualify your assumptions before you post them and claim they are factual statements. just because you are writing long paragraphs, it does not mean you actually understand what you are talking about. LCD blocks 100% of the light. It uses two polarized filters at 90 degree angles. LC bends or leaves the light as is to let it go through or block it. In order to work (depending on the design) you will need at least one polarizing filter and since they block 50% of the light, that would mean only half of the UV would pass thorough. Additionally, some screens might have a UV protective coating that could block almost all of the light. Again, all said and done, there is no doubt in my mind that this can be done, but how well or is it worth it are the questions. Printing a piece of inkjet film is going to be significantly simpler for most ppl.pierreI really can't bother with responding to you anymore Pierre. It is more than obvious that you don't know how this works, or how easy it is to do. First... your statement that LCD blocks 100% of the light is false. The liquid crystals are arranged so that they PASS THE LIGHT in the OFF STATE. Therefore without even having the panel on, I can see light passing through, it is TRANSPARENT. Yes the polarizing filters block some of the light passing, you overcome this with HIGH POWER like any "professional grade" exposure unit does. I even get it to cure with cheap lights and low power and just really long times but I'm not saying that is useful or professional grade. What happens is the charge sent to the crystals jumbles them up so they don't turn the light back 90 degrees and it doesn't pass - that is the ON state which actually makes the pixel block the light. The amount of power sent is how they get a variation in how much light is blocked (percentage of the crystals jumbled up vs. arranged to pass the light)The polarizing filters are already UV blocking but not 100%, so it works. You don't need another polarizing filter. It doesn't matter one bit to me if you have doubts in your mind that it will work, because it already does, LOL! HILARIOUS!! And then people laughing about you not even reading my post... but you respond??? Do as you say, not as you do? Why should I bother reading your posts anymore then? Just like with the color separation stuff, you think you know what you're talking about but you fail to comprehend the most basic and fundamental aspects of how it all works in the real world. Your "awards" are for the art, not for the reproduction or printing. The industry doesn't even know how to standardize simulated process, but I've finally done that myself. It is amazing to see how it actually SHOULD work and that nobody has bothered to do any R&D to discover that... it proves exactly why separators do what they do and why the printers do what they do with the seps, but again it is a mathematical process and doesn't require some artistic human hand to make it work, only a decision on what mode you want to print,(stochastic, interlock, dot-on-dot, flamenco, overprint, or simulated process or a mix of them or hybrid depending on various factors that make each method have some pro's and con's) and it proves again how ignorant it all is when the blind lead the blind in a whole industry. But please, keep bragging about your awards that are judged on the art and not the printing. Did they have the same printers print the same design and yours was the most accurate to the design you intended (oh yeah, not the original art, but the one you changed to have more "punch" lol.).... So did they measure your version with the "punch" compared to the print and did they give you a % differential? You could compare different art from different printers if you know how to measure the art-to-print differences. But here is most likely what happens... "judges" take a "look" at the "prints" and they vote which one they think is "the best print". LOL. The very definition of arbitrary. https://en.wikipedia.org/wiki/Liquid-crystal_display"Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, and two polarizing filters (parallel and perpendicular), the axes of transmission of which are (in most of the cases) perpendicular to each other. Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer."I am only writing this so others would not be fooled by your incorrect statements. Above quote is from Wikipedia. . .pierreSo you clearly can't read or comprehend what this is saying?"Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer."Therefore.... WITH the Liquid Crystal between the polarizing filters, light passing through the first filter will be re-oriented so it PASSES the second filter.Read it, comprehend it. Admit you're wrong and let's move on. just for you and your engineers, I'll spell this out again (try reading slowly, maybe you'll get it this time!).Before the light hits the Liquid Crystal part, it has to go through a polarizing filter. Polarizing filters by nature eliminate all the light in one direction (out of two, so 50% of the light). Thus, light has been reduced by 50% before it ever enters the LCD part.pierre

LCD blocks 100% of the light. It uses two polarized filters at 90 degree angles. LC bends or leaves the light as is to let it go through or block it. In order to work (depending on the design) you will need at least one polarizing filter and since they block 50% of the light, that would mean only half of the UV would pass thorough. Additionally, some screens might have a UV protective coating that could block almost all of the light. Again, all said and done, there is no doubt in my mind that this can be done, but how well or is it worth it are the questions. Printing a piece of inkjet film is going to be significantly simpler for most ppl.pierre

You might want to consider sleeping on it before you post any answers in the future.pierreLOL!!!! Now you're taking it to personal attacks. Again, typical. This is why I don't bother with this board. Your statements are not factual, they are unqualified statements that are assumptions about the physical aspects, not facts. You said: "something to remember here is that the polarized glass of the LCD display will stop 50% of the light from coming through" Which LCD panel are you talking about? Which polarizing film? Do you think 50% is a factual number associated with the amount of light passing through the LCD, the amount of actual UV, etc etc.... maybe its 25% maybe its 75%, maybe its 50%, but you clearly just threw that number out there without doing research or 'qualifying' the statement so it could be considered factual. Again, it isn't really a hurdle to overcome any more than typical hurdles in exposure based on the tolerances and variables required. Yes, there is a piece of polarizing film before the LCD and after the LCD, it is how it works, but simply saying it "will stop 50% of the light" is not a factual statement, it is a generalization that could be way off when you actually qualify it. So do you mean 50% of the UV light at the 405nm wavelength will be stopped through a "brand/manufacturer specific" panel, which needs to be specified which one to be qualified, and of this light at a given moment in time from what is reaching the panel to what it coming through the panel, do you know the ratio of how much light is coming through the "blocked" areas of the stencil, and do you know the comparison to this vs. the amount of light going through a piece of film and what makes it through the blocked areas? For your statements to be factual you would need to qualify it with all of those actual physical system connections. Otherwise it is as I stated before, just an assumption you are making. Do you understand the ratio between how much UV is passing and how much is being blocked? The contrast ratio for the LCD might actually be greater than that of "specific film" with "specific ink/rip/density" or compared to DTS with the wax/ink, or with DLP. DLP probably has the highest contrast ratio, since there is no "blocking" stencil, it is only exposing direct UV Laser or LED light onto the emulsion. LCD might have the second highest contrast ratio because the "dark" areas might be blocking more light compared to what is passing, comparing with what film or DTS is blocking and allowing to pass. You might want to qualify your assumptions before you post them and claim they are factual statements.

Wow just wow. That only personal insults in this entire thread are from your posts Full Spectrum. But you just tried to convince me of the opposite. Listen when every single person that responds to you agrees you are the abrasion here at what point to you cede to that reality? It is going to be far harder to convince anyone of your ideas if your posts are littered with so much vitriol. You are talking to very intelligent successful people like they are ten year olds. All I see you have to show at 35 is you know how to push a squeegee for another printer. As for 4k or even 8k monitors I would not be very happy when a pixel shits the bed then what? Replace an expensive monitor or have a permanent spot that can never expose?
you are referencing a photography CIRCULAR filter which different.Polarizing filter in the LCD display eliminates half of the light rather than reorienting. Photography polarizing filter has a different purpose.so it cuts out 50% of the light. Yes, you can increase the light to make up for it, that was never in dispute. The issue was your misunderstanding of how the lCD works and the polarizing filters that remove half the light (which is a wave and a particle and pulses in all directions).Here's another wikipedia image that shows what's going on:light has a vertical and horizontal component to the wave. Individual filters remove one of the components depending on which way they are oriented. yes, I have taken my physics classes and done the experiments with these. I also use them in photography (used to use the linear and now use circular polarizers).and I am done defending this as I would imagine most other ppl will not be as dense and will get it by now. . .pierre pierre
I must have missed that in your numerous word vomits, sorry. In response to your assertions that Pierre doesn't know the percentages of UV the LCD blocks (specifically in the range needed to expose the emulsions we use): apparently you don't either. Fortunately that is discussed at length on the forum you have apparently already read (and forgotten). Hint: it's significantly more than 50%. In fact, they even have the decency to link to a handful of articles and studies (like where people used science and stuff!) that specifically address that topic. They even discuss related issues like the fact that increasing the intensity of the light source inversely affects the contrast ration of the LCD! (uh oh) Food for thought as you continue to test with brighter lights or the sun...Like I said, that thread discusses many of the issues that make this a waste of time for our industry.Your math above is also irrelevant when discussing what it would take to get even a comparable setup using this technology vs a cheapo inkjet and film setup. You will literally not get a screen with the same quality for the same price, and even when you factor in consumables it would take a long time and a lot of headaches. The upfront cost would also make it prohibitive for your proclaimed target demographic to begin with, and at a certain point it would simply make more sense to upgrade to other proven technologies. You are also completely ignoring the issues of a printer being plug and play vs having to build this thing (easy for some, but probably not most people), the fragility of the LCD vs film/ink, and numerous other considerations...
Quantum physics now? Quantum Physics deals at the atomic level, not sure how quantum physics has anything to do with Strong Nuclear forces and gluons but ok.Your macros and scripts in Corel and Photoshop(which I think no one can actually use if I recall) is something a hundred people have done before you and will continue to do so. Still pushing/pulling a squeegee, does that impress your engineers and scientists when you pitch your arguments to them? I digress that is pretty petty of me, Einstein failed school and filed patent claims and he turned out to be the smartest physicist ever.
Seriously why not ban this guy, is there even one person that would like him to stay?
