The present invention relates in part to a print method for an arbitrary grey scale image on a transparent substrate such as glass. The present invention makes use of a printer that can print in continuous grey tones. The printed material should be transparent and resistant to the light which passes through it in a projection system. The present invention also provides a continuous grey scale filter made by a printing techniques using liquid inks or toners. Such a continuous grey scale filter can be used for blending multiple images in a multichannel projector system. The present invention also provides a multichannel projector system using the continuous grey scale filter.
A projection system comprising:
A method of projecting multiple images using at least two projectors that project at least a first and a second image respectively, the method comprising:
A printing process for producing a continuous tone blend filter with a constant thickness for use in a projection system, comprising the steps of additively depositing at least one coloured component and at least one colourless component at least contiguous to one another to provide a constant layer thickness with a continuous tone varying from zero to an optical density of at least 1.5 on a transparent support;
A continuous tone blend filter for use as an optical mask in a multichannel projector system, wherein the continuous tone blend filter is formed by printing onto a transparent substrate with liquid toners or inks, continuous tone variation being provided by bleeding.
