Laser graffiti how does it work

This also means that powerful chemicals cannot be used to clean away the graffiti, either. Lasers, with their high precision and minimal chemical impact, have emerged as the tool of choice to tackle this problem. The principle behind laser cleaning is astonishingly simple — a laser beam, with its narrow area of focus, carries enough heat to vaporize particles that cross its path. The trick is getting the numbers right. A laser beam of very high intensity could damage a surface instead of vaporizing only the foreign particles, whereas a beam of very low intensity would have no discernible effect.

Laser cleaning to remove graffiti off stone also depends on the type of stone. A coarse-grained stone would allow foreign particles to penetrate so deep that it would be difficult for the laser beam to even reach them.

A fine-grained stone, on the other hand, while blocking the entry of foreign particles, would also melt yes, melt! They also tested the effect of these beams on the internal composition of the granite. Selecting the right energy and hence, wavelength of a laser beam is like walking a tightrope: the energy of a beam needs to be the minimum possible to avoid melting biotite the most laser-sensitive mineral in granite and thus damaging the stone, but also needs to be adequate to initiate the removal of paint.

It is also possible to have the audience draw themselves with the laser graffiti technique so that an interactive experience is created.

Our promotion team can immediately distribute your information to curious passers-by. Laser graffiti is best seen when it is dark, so these actions are always performed in the evenings. The laser graffiti, sometimes too laser tag mentioned, unlike wild beaming, cannot be used while driving. It is also not possible to project in a vacuum, there must always be a surface available on which to project.

With our laser graffiti application we can make temporary line drawings on buildings and objects that disappear after the projector has been switched off. View the practical information and frequently asked questions about our laser graffiti campaigns. The laser graffiti can be scheduled 7 days a week, but it must be dark during the execution.

The maximum format is approximately m2, but this depends on the possible distance to the object. The preparation time for a laser graffiti campaign is on average 7 working days, rush is possible. Laser graffiti falls under the so-called 'guerrilla marketing', we do not apply for a license.

Laser projections are the perfect means to make logos, texts and advertisements clearly visible from a great distance in the dark. A laser projection must always take place on a building or object, unfortunately making a projection visible in a vacuum is not possible.

A projection can be done in many colors, so we can convert any logo and image into a projectable visual. With our laser projections you inform and amuse your target audience in a spectacular and striking way without burdening the environment.

We also provide permanent projections on company buildings as well as spectacular ones laser shows during anniversaries, presentations, company parties and events. We would like to design the most effective projection together with you. Laser graffiti falls in a gray area in terms of laws and regulations. It is therefore generally not possible to opt for this form of guerrilla marketing apply for a permit. A subtle and thoughtful approach when executing is necessary to prevent any complaints. Of course we are specialized in this and we can make a good estimate of the im possibilities in advance.

When the laser tag It is sometimes possible to apply for permission or a permit for or in consultation with a city, municipality or province, or around a common or public purpose.

Do you need a projector to be displayed on a surface In order for the laser graffiti to work Reply 4 years ago.

Hi, for this setup, is it possible for using win8 and later? Reply 5 years ago. Hi pradawinata, we've never used the software in win8, I would recommend using windows vista or xp. For the camera any fair quality Infra red would help, of course the more powerful the camera the farther you can track the laser and therefore the smoother will be. Reply 7 years ago on Introduction. Estoy siguiendo los pasos que indicas y estoy por lo pronto buscando todo el material necesario.

I'm confused. It is because I cannot afford a projector, and need borrow from college. The college projectors are old model. I am beginner with no knowledge on this, by reading and looking through several time, I not understand why the infrared camera needed. I google the infrared camera, which one you recommend? Your reply will be appreciated. Thank you. Reply 9 years ago on Introduction. My Dear friend instrumata, i recommend DLP chip projector because of some color features, but is not necessary, any respectable projector would do, its all about the distance where you are projecting from and the intensity of brightness you want to ahve in your proyected area.

Any projector with a x resolution would do.
