Not sure if this is in the correct forum so apologies if i’ve b@gggered up.
How does this work?

Which bit Karl?
If it’s rear projection; it’s a special lens for the projector. Throws the image on to the screen differently and from a shorter distance than front projection. -
are you sure Harry?
We haven’t used the Vikuiti film but we had and alternative from another company I sourced from in Canada, around 5 years ago.
I had it in our reception area window using a cheap £200 projector mounted on the ceiling.
it worked a treat. but as you can imagine, the quality of the projector, the scren adjusting sizes, resolution etc all comes into play. still, ours did the job very well. if i remember right you must have the projector sitting at a specific angle to get the best results.as i said, this was not Vikuiti, just an alternative rear projection film.

Maybe it is as simple as that and the film does the trickery. I’ve always understood ‘rear projection’ to use a special lens. Maybe things have moved on. 😳

Ask how much it costs first 😛

Vikuiti is a rear projection film from 3M (looks like a thick speckled Black transparent film)
Very easy to install or apply the film as it is self adhesive
In theory you can project on any glass and any situation ….. and within reason as large as you like
It doesn’t need a special lens but depending on the application, ambient light and size you wish to create will determine how powerful the projector needs to be and how bright the projected images will be and as Rob stated earlier the angles where the projector needs to be placed can be critical.
….. and as Jason is inferring its not as cheap as a monomeric printing film

Hi Stuart,
out of interest…
Can Vikuiti be tiled and then projected onto or does the join create problems?I only purchased a couple of bits of the rear projection film, so didn’t have anything i could experiment with. i.e. tiles
also, can Vikuiti be cut in a cutting Plotter?
I know the film can be cut into almost any sort of shape then projected onto, but wondered if this was done in a plotter or would a flatbed cutter be needed?again, i never got to experiment this far with what i had.
however, one of the two i received had no chance in a cutter, i didnt need to test it. whilst the other was pretty thick and looked like a heavy grade glass etch film, I thought it might have had a chance.I remember the Vikuiti girl on the Wm. Smiths stand at Sign & Digital, thought that was very clever and gave another possibilty of its use.
Even if folk were not interested in what she had to say, it had everyone including myself stopping to have a look.<embed width=”585″ height=”467″ quality=”high” bgcolor=”#000000″ wmode=”transparent” name=”main” id=”main” allowfullscreen=”false” src=”http://www.isigntube.com/player/vPlayer.swf?f=http://www.isigntube.com/player/vConfig_embed.php?vkey=e77f13a6d184dbf1232f” type=”application/x-shockwave-flash”>

Hi Rob
Yes to both questions
If you tile the only distraction is how you tile i.e. butt joint or with a window framing system – The butt joint works quite nicely and at large format even multiple panels with a narrow frame sort of disappear from the eye – What is more of an issue is being able to project bright enough and large enough at these mega sizes. In theory it is possible to use multiple projectors and some clever jiggery pokery software to make mega sized screens ….. however this option is by no means cheap
Regarding cutting I would think that any decent plotter will cut the Vikuiti , we use Zund flatbeds but I know many who buy a thick sandblast product from us that is a similar thickness have no issues cutting on a Graphtec or Summa – we have a demo Summa unit here so will arrange an internal test ….. there goes the profits for the month 😉
You can pretty much cut any shape with Vikuiti and then it is down to masks on your imagery so you dont blind anyone looking straight at the image with light bleed

3m Film can be joined – we did a large install of 2.4m x 12m rooms – which works fine
Its all about the right projector and size against cost – so many of our dealers get it wrong
We cnc cut our rear projection film with Plotter – flat bed and roland roller type with no issue
happy to help

Very impressive Geof, is this how cinemas are done?

Cinemas?
they are face projecting are they not Dave?
surely you have looked behind you only to see the projected light above every ones heads?.

Home Cinema in a single piece of film will do 3m x 2m in rigid and 1.54m x whatever wide
We have done 3m x 4m single rear projection without a seam.
The job on the image was a 6m x 3m interactive immersive room for Essex University for one of our
Rear projection is perfect for smaller cinema – projector throw will not work on large screens – unless outdoors

my local cinema has some smaller screens, quality is very good and it is rear

HD Projectors are getting cheaper so are reasonable surround sound systems
perfect system for a pub or small theatre cinema screen
:police: Please take a moment to look over our Board Rules.

if a rear projecting film is used in something like a small home cinema or the like. surely this would be a space killer as you need to allow for the projection space at the rear? Ide imagine the bigger the screen the bigger the projection space?
-
Rob, you can get projector’s now with a very short ‘throw’ or projection space, but as you say for a home cinema system I couldn’t see you having rear projection. My mate’s club has a full wall screen say 20′ x 10′, I was looking for the projector way back but it was about 5′ away!
-
Thanks David, i didn’t realise you could get them so close but still project over such a large screen area.
as you say though, even if its 5-6 ft away projecting onto an area of 8ft by 8ft thats the size of a kids bedroom behind the TV screen. which could be argued it could be used for storage, but as its a projecting room, nothing can impede the projection so it would have to be more or less "empty" space behind the screen. 😕

Just a quick question about the legal side of things.
How do you stand from a planning/council point if you place something like this in a shop window on the main high st.
While I really like it, it could be a huge distraction to the moterists.
-
Good point Denise, not really thought about it or think many will have considered. For me its been more retail park and big shopping malls I’ve had the interest in this sort of thing. I guess in these type of places its not going to be an issue. certainly not exhibition and the like using even the virtual manikins.

Getting the light output from the projector could present issues in daylight conditions unless the lumens are up at about 3500, most rear screen material requires that you are almost directly in front of the screen and not veiwing at an angle, so the distraction to traffic is not an issue, seen these used a lot in Estate agent displays, and hair dressers windows. The rear screen material refracts the light in order that you cannot see the light source from the projector bulb, this is why the image defuses at an acute angle. I have two short throw projectors, Panasonic 3700 lumens, and the distance from a wall or a screen required to obtain an image size 8ftx10ft is approx 12 inches, these can be used as front or rear projectors, they can also be ceiling mounted to allow the use of the area behind the screen, you can keystone correct on the vertical and horizontaal plane . The size of the projector is approx 18 inches by 15 and stands about 5 inches high. data / video & HDMI inputs. This kind of tech has moved so fast in a short space of time, they are also very handy to use in the sign shop , for painting large scale back drops etc. just my threepence worth

This might be a silly question, but what format do the projectors take, is it film reel as when I was small and my parents had a cine camera?

Denise, the term projector is the only similarity between the old style 8mm super8 and 16mm film formats, the light output for those projectors was in watts the average film projector bulb was about 300 watts, the new projector are a lot brighter , the new projectors can accept several different inputs, they will accept video / DVD inputs for that type of player, they can accept computer inputs from PC or Mac, also the newer format HDMI , for video game consoles , like Xbox Ps3. So if you like the projector give you the option to view anything you can view on a screen , a larger version of what you see on your tv , pc , laptop, computer screen.
So if you wanted to view old style movies these would need to be transfered to a newer format, DVD, QuickTime, Avi, there are companies who do what is still called tele cine transfer, not sure if I have given you the answer you were looking for, but if not let me know, all the best , and I am now ready for my big close up -
Found this recently, looks as if they cover all the bases
