A gravure printing system comprising a gravure cylinder having a first plurality of discrete cells disposed upon an outer surface thereof is disclosed. Each cell of said first plurality of discrete cells has a nominal diameter and is capable of receiving a fluid that is a first combination of at least two primary fluids. The fluid is fluidically displaceable through a discrete channel having a single entry point at said first position and a single exit point into a first cell of said first plurality of discrete cells. The outer surface has a metal plating disposed thereon. The metal plating reduces the nominal diameter of each cell of the first plurality of discrete cells.

A system for producing a paper product. The system includes a paper machine, an analysis tool, and a converting line. The paper machine forms a paper web having a plurality of sections, inspects the paper web to identify web properties, and marks the paper web with a plurality of marks. The analysis tool assigns action scores to each section of the paper web based upon the identified properties that section of the paper web. The converting line reads at least one of the plurality of marks on the paper web, obtains the action score associated with a second one of the plurality of marks, calculates a distance between the at least one mark read by the reading unit and the second one of the plurality of marks, and changes at least one operational parameter of the converting line when the calculated distance is less than a threshold.

[Problems] Provided is a discoloring body which is discolored by application of water and has high glossiness and is excellent in applicability to various fields such as a toy field, a decoration field, and a design field. [Solution] A discoloring body including a supporting body, a porous layer in which a low refractive index pigment is fixed in a dispersed state by way of a binder resin, and a glossy resin layer, in which an occupancy area ratio of the glossy resin layer is 1% to 95% with respect to a 1 cm square at any position in the porous layer.

A method of controlling a paper product converting line. The method includes unwinding a paper web from a parent roll on a converting line, the converting line having a plurality of operational parameters, the paper web including a plurality of sections in a sequence, and a plurality of marks, each mark being associated with an action score, at least one action score having an action value, reading at least one of the marks, obtaining the action score associated with a second one of the marks, the second of the marks being a next mark with an action value after the one read mark, calculating a distance between the at least one read mark and the second one, changing at least one operational parameter of the converting line based upon the action score, and converting the paper web into a paper product.

A method of controlling a converting line that produces a paper product. The method includes unwinding a paper web from a parent roll on a converting line having a plurality of operational parameters. The paper web includes a plurality of sections and a plurality of marks, with at least one mark assigned to each of the plurality of sections and each mark associated with a paper rating. At least one of the plurality of marks is read with a mark reading unit. The paper rating associated with the at least one mark read by the reading unit is obtained. At least one operational parameter of the converting line based upon the obtained paper rating is changed. The paper web is converted into a paper product.

A converting line for producing a paper product. The converting line includes a paper web being unwound from a parent roll. The paper web has a plurality of sections with at least one mark, associated with an action score, assigned to each of the plurality of sections. The converting line also includes a mark reading unit, which reads one of the plurality of marks on the paper web. The converting line further includes a controller configured to obtain the action score associated with a second one of the plurality of marks; to calculate a distance between the one mark read by the reading unit and the second one of the plurality of marks; and to change at least one operational parameter of the converting line based upon the action score of the second one of the plurality of marks when the calculated distance is less than a threshold.
