necessarily true of every embodiment it is possible as shown in fig6 to space the element from the surface by varying the optical parameters of the element in fact for obvious reasons it is preferred in many instances that there be no physical contact between the element and the imaging member zero clearance is undesirable for a number of reasons e g the interference with the charge and development steps when the lenticular element 14 is used in actual contact with the imaging member during exposure it is obvious that the development step may present difficulties in some situations it is necessary to remove or displace the element to a location sufficiently remote to allow heating or softening of the member on the other hand it is not necessary to remove the lens if it is made of a material which is not affected by the heat or solvent used to develop the member in such a structure it is feasible that the lenticular element be an integral part of the imaging member the application of a solvent or solvent vapors in such a situation would then depend upon the porosity of the layered portions of the imaging member the instant invention has a number of distinct advantages over the prior art systems for example it is not necessary for the inventive lenticular screen to be in contact or integral with the imaging member during viewing thereby providing reusability and decreased manufacturing costs furthermore the reusable feature of the screen allows imaging from either side more flexibility in.
