The one or more pretreatment compositions are selected based upon a parameter of the medium. ## Claims ### Claim 1 A printing system comprising: a media transport configured to transport a medium; a parameter obtaining unit configured to obtain at least one parameter of the medium; a selector unit configured to select one or more of a plurality of pretreatment compositions to be formed on the medium based on the least one obtained parameter, wherein the at least one parameter comprises at least one of reflectivity and absorptivity; one or more pretreatment applicators configured to form the selected one or more of the plurality of pretreatment compositions on the medium; and a fluid applicator configured to apply fluid to the one or more pretreatment compositions on the medium to form one or more images. ### Claim 2 (depends on 1) The printing system of claim 1, wherein each of the plurality of pretreatment compositions comprise: a liquid vehicle; a polyvalent metal salt as a fixing agent; and a latex resin having an acid number of less than 20. ### Claim 3 (depends on 1) The printing system of claim 1, wherein the fluid is anionic and wherein the least one pretreatment composition is anionic. ### Claim 4 (depends on 1) The printing system of claim 1, wherein the media transport is configured to move the medium from the pretreatment applicator to the fluid applicator in under five seconds. ### Claim 5 (depends on 1) The printing system of claim 1, wherein the system omits drying devices in a print zone of the fluid applicator. ### Claim 6 (depends on 1) The printing system of claim 1, wherein the pretreatment applicator is configured to apply the at least one pretreatment composition in a concentration of between 1% and 20% by weight of salt and between 1% and 70% by weight of resin covering the medium in a range of 0.3 to 20 gsm. ### Claim 7 (depends on 1) The printing system of claim 1, wherein the parameter obtaining unit comprises a medium characteristic detector. ### Claim 8 (depends on 1) The printing system of claim 1, wherein the parameter obtaining unit comprises an input configured to receive at least one characteristic of the medium or identity of the medium from a person. ### Claim 9 (depends on 1) The printing system of claim 1, wherein the parameter obtaining unit comprises: a memory containing physical characteristics of a plurality of media; a medium identifier configured to identify the medium and to obtain at least one physical characteristic of the medium from the memory based upon an identity of the medium. ### Claim 10 (depends on 1) The printing system of claim 1, further comprising an input device configured to receive an image durability selection, wherein the selector unit is configured to select the at least one of the plurality of pretreatment compositions based upon the received image durability selection. ### Claim 11 (depends on 1) The printing system of claim 1, wherein the selector unit is configured to select a first pretreatment composition having a first percentage of a matte fluid for a medium having a first gloss level and a second pretreatment composition having a second percentage of the matte fluid greater than the first percentage for a medium having a second gloss level less than the first gloss level. ### Claim 12 (depends on 1) The printing system of claim 1, wherein the selector unit prepares the selected one or more of the plurality of pretreatment compositions from pretreatment composition ingredients. ### Claim 13 A printing system comprising: a media transport configured to transport a medium; a parameter obtaining unit configured to obtain at least one parameter of the medium; a selector unit configured to select one or more of a plurality of pretreatment compositions to be formed on the medium based on the least one obtained parameter; one or more pretreatment applicators configured to form the selected one or more of the plurality of pretreatment compositions on the medium; and a fluid applicator configured to apply fluid to the one or more pretreatment compositions on the medium to form one or more images, wherein each of the plurality of pretreatment compositions comprise: a liquid vehicle; a polyvalent metal salt as a fixing agent; and a latex resin having an acid number of less than 20. ### Claim 14 A printing system comprising: a media transport configured to transport a medium; a parameter obtaining unit configured to obtain at least one parameter of the medium; a selector unit configured to select one or more of a plurality of pretreatment compositions to be formed on the medium based on the least one obtained parameter; one or more pretreatment applicators configured to form the selected one or more of the plurality of pretreatment compositions on the medium; and a fluid applicator configured to apply fluid to the one or more pretreatment compositions on the medium to form one or more images, wherein the fluid is anionic and wherein the least one pretreatment composition is anionic. ### Claim 15 A printing system comprising: a media transport configured to transport a medium; a parameter obtaining unit configured to obtain at least one parameter of the medium; a selector unit configured to select one or more of a plurality of pretreatment compositions to be formed on the medium based on the least one obtained parameter; one or more pretreatment applicators configured to form the selected one or more of the plurality of pretreatment compositions on the medium; and a fluid applicator configured to apply fluid to the one or more pretreatment compositions on the medium to form one or more images, wherein the media transport is configured to move the medium from the pretreatment applicator to the fluid applicator in under five seconds. ### Claim 16 A printing system comprising: a media transport configured to transport a medium; a parameter obtaining unit configured to obtain at least one parameter of the medium; a selector unit configured to select one or more of a plurality of pretreatment compositions to be formed on the medium based on the least one obtained parameter; one or more pretreatment applicators configured to form the selected one or more of the plurality of pretreatment compositions on the medium; and a fluid applicator configured to apply fluid to the one or more pretreatment compositions on the medium to form one or more images, wherein the pretreatment applicator is configured to apply the at least one pretreatment composition in a concentration of between 1% and 20% by weight of salt and between 1% and 70% by weight of resin covering the medium in a range of 0.3 to 20 gsm. ### Claim 17 A printing system comprising: a media transport configured to transport a medium; a parameter obtaining unit configured to obtain at least one parameter of the medium; a selector unit configured to select one or more of a plurality of pretreatment compositions to be formed on the medium based on the least one obtained parameter; one or more pretreatment applicators configured to form the selected one or more of the plurality of pretreatment compositions on the medium; and a fluid applicator configured to apply fluid to the one or more pretreatment compositions on the medium to form one or more images, further comprising an input device configured to receive an image durability selection, wherein the selector unit is configured to select the at least one of the plurality of pretreatment compositions based upon the received image durability selection.
