Abstract
A toner image that combines pictorial information with text or graphic information is made glossy only in the pictorial portion. A clear gloss enhancing toner is selectively applied to the portion of the image that is pictorial as determined by a suitable manual input or electronic analysis of the image.
Claims10
A method of forming a toner image having visibly distinct segments of varying texture of gloss, from input image information, said method comprising:
- defining a portion of the input image information corresponding to a distinct segment that is to be of higher gloss or less texture, and
- producing the toner image from the input image information on a receiving sheet, which toner image includes a clear gloss producing or texture reducing toner selectively in said visibly distinct segment.
A method of forming toner images having portions of varying textures or gloss, said method comprising:
- determining a first portion of an image which contains pictorial subject matter and a second portion of an image which does not contain pictorial subject matter,
- producing a plurality of toner images on a receiving surface, said plurality of images including a toner image made up of a clear gloss enhancing toner, the gloss enhancing toner image conforming to the first portion of the image,
- superposing said toner images on a surface, and
- fixing said toner images to said surface.
A method of forming a toner image on a receiving sheet, which toner image includes a first portion which is primarily pictorial and a second portion of said image which is primarily text or graphics, said method comprising:
- forming a series of electrostatic images, including at least first and second electrostatic images corresponding to different color components of the desired final image and a third image, corresponding to the first portion of the image,
- applying different color toner to said at least first and second electrostatic images to form different color toner images defined by the first and second electrostatic images,
- applying a low melting point gloss enhancing toner to said third electrostatic image to form a toner image corresponding to the first portion of the final toner image, and
- superposing said images in registration to create a multicolor image having increased gloss in the pictorial portion.
A method of forming a final toner image on a receiving sheet, which final toner image includes a first portion which is primarily pictorial and a second portion, said method comprising:
- forming a series of five electrostatic images, the first four of said images corresponding to color information making up components of the desired final image and the fifth electrostatic image corresponding to the first portion of the final image,
- applying black, cyan, magenta and yellow toners to four of said electrostatic images, respectively, to form different color toner images,
- applying a transparent toner having a lower viscosity than at least said black toner to the fifth electrostatic image to create a toner image corresponding to the pictorial portion of the final image,
- superposing the five toner images in registration on a receiving sheet to form a multicolor toner image with a gloss enchancing toner in the pictorial portion,
- fixing said toner image to said receiving sheet under conditions of pressure and temperature providing a glossy appearance in the pictorial portion of the image and a less glossy appearance to the image in the non-pictorial portion.
