Disclosed is a planographic printing plate precursor comprising a support, and provided thereon, an image forming layer, a first outermost layer on the image forming layer side and a second outermost layer on the side of the support opposite the first outermost layer, the first and second outermost layers containing a lubricant component, which is manufactured either by a method comprising the steps of preparing a planographic printing plate precursor comprising a support and provided thereon, an image forming layer so that only the first outermost layer contains a lubricant component and winding the resulting precursor in the roll form, or by a method comprising the steps of preparing a planographic printing plate precursor comprising a support and provided thereon, an image forming layer so that only the second outermost layer contains a lubricant component and winding the resulting precursor in the roll form.
A planographic printing plate precursor comprising a support, and provided thereon, an image forming layer, a first outermost layer on the image forming layer side and a second outermost layer on the side of the support opposite the first outermost layer, the first and second outermost layers containing a lubricant component, wherein the planographic printing plate precursor is manufactured either by a method comprising the steps of preparing a planographic printing plate precursor comprising a support and provided thereon, an image forming layer so that only a first outermost layer on the image forming layer side contains a lubricant component and winding the resulting printing plate precursor around a spool in the roll form to transfer a part of the lubricant component of the first outermost layer to the second outermost layer, or by a method comprising the steps of preparing a planographic printing plate precursor comprising a support and provided thereon, an image forming layer so that only a second outermost layer on the side of the support opposite the first outermost layer contains a lubricant component and winding the resulting printing plate precursor around a spool in the roll form to transfer a part of the lubricant component of the second outermost layer to the first outermost layer.
A planographic printing plate precursor comprising a support and provided thereon, an image forming layer, a first outermost layer on the image forming layer side and a second outermost layer provided on the side of the support opposite the first outermost layer, the first and second outermost layer containing a lubricant component and having a coefficient of static friction of from 0.05 to 2.00, wherein the planographic printing plate precursor is manufactured by a method comprising the steps of preparing a planographic printing plate precursor comprising a support and provided thereon, an image forming layer so that only a first outermost layer on the image forming layer side contains a lubricant component and has a coefficient of static friction of from 0.05 to 2.00, and winding the resulting printing plate precursor around a spool in the roll form to transfer a part of the lubricant component of the first outermost layer to the second outermost layer, so that a second outermost layer provided on the side of the support opposite the first outermost layer has a coefficient of static friction of from 0.05 to 2.00.
A method of printing employing a planographic printing plate precursor, comprising a support and provided thereon, an image forming layer, a first outermost layer on the image forming layer side and a second outermost layer on the side of the support opposite the first outermost layer, the first and second outermost layers containing a lubricant component, wherein the planographic printing plate precursor is manufactured either by a method comprising the steps of preparing a planographic printing plate precursor comprising a support and provided thereon, an image forming layer so that only a first outermost layer on the image forming layer side contains a lubricant component and winding the resulting printing plate precursor around a spool in the roll form to transfer a part of the lubricant component of the first outermost layer to the second outermost layer, or by a method comprising the steps of preparing a planographic printing plate precursor comprising a support and provided thereon, an image forming layer so that only a second outermost layer on the side of the support opposite the first outermost layer contains a lubricant component and winding the resulting printing plate precursor around a spool in the roll form to transfer a part of the lubricant component of the second outermost layer to the first outermost layer, the method comprising the steps of imagewise exposing the planographic printing plate precursor to laser light to form an image on the planographic printing plate precursor, and supplying ink to the exposed planographic printing plate precursor.
