## Abstract

It is hereby disclosed a textile printing method comprising a controller to: receive a print job; and determine a print area of a garment based on the print job; wherein the controller is to instruct a printhead comprising a pre-treatment liquid to eject a pre-treatment liquid in a pre-treatment area of the garment being the pre-treatment area associated to the print area; and to instruct a printhead comprising printing fluid to print the print job on the print area.

## Claims

### Claim 1

A textile printing method comprising:
receiving a print job;
determining a print area of a garment based on the print job;
instructing a printhead comprising a pre-treatment liquid to eject the pre-treatment liquid in a pre-treatment area of the garment associated to the print area;
instructing a printhead comprising printing fluid to print the print job on the print area;
determining a servicing area of the garment based on the pre-treatment area such that a size of the servicing area is based on the size of the pre-treatment area; and
instructing the printhead comprising printing fluid to perform spitting routines in the servicing area exclusive of the pretreatment area.

### Claim 2 (depends on 1)

The method of claim 1 wherein pre-treatment area contains the print area.

### Claim 3 (depends on 1)

The method of claim 1 wherein the controller is further to apply an opaque fluid at least partly within the print area and to apply the printing fluid over the opaque fluid.

### Claim 4 (depends on 1)

The method of claim 1, wherein the servicing area is within an area complementary to the pre-treatment area.

### Claim 5 (depends on 1)

The method of claim 1 wherein the textile is a dark textile.

### Claim 6 (depends on 5)

The method of claim 5 wherein the dark textile is a textile with a lightness below 50 according to CIELAB color space.

### Claim 7 (depends on 1)

The method of claim 1, wherein the garment is a shirt or a cap.

### Claim 8

A textile printer that comprises:
a set of marking printheads, wherein each marking printhead ejects a marking fluid towards a garment;
a set of pre-treatment printheads, wherein each pre-treatment printhead ejects a pre-treatment liquid towards the garment; and
a controller to receive a print job and control the set of marking printheads and the set of pre-treatment printheads;
wherein the controller is to receive a print job and define, on the garment, a pre-treatment area and a print area based on the print job
wherein the controller is to instruct the pre-treatment printheads to eject pre-treatment liquid on the pre-treatment area and to instruct the marking printheads to eject marking fluid on the print area,
wherein the controller is to define a servicing area on the garment based on the pre-treatment area such that a size of the servicing area is based on the size of the pre-treatment area, and
wherein the controller instructs the marking printheads to perform a servicing operation in the service area.

### Claim 9 (depends on 8)

The printer of claim 8 wherein the servicing operation includes ejecting drops of marking fluid on the service area.

### Claim 10 (depends on 8)

The printer of claim 8 wherein the servicing operation includes spit-on-page servicing.

### Claim 11

A non-transitory machine-readable medium storing instructions executable by a controller, the medium storing instructions to control a textile printer to:
receive a print job;
determine a print area of a garment based on the print job;
instruct a printhead comprising a pre-treatment liquid to eject the pre-treatment liquid in a pre-treatment area of the garment associated to the print area;
instruct a printhead comprising printing fluid to print the print job on the print area;
determining a servicing area of the garment based on the pre-treatment area such that a size of the servicing area is based on the size of the pre-treatment area; and
instructing the printhead comprising printing fluid to perform spitting routines in the servicing area exclusive of the pretreatment area.

### Claim 12 (depends on 11)

The non-transitory machine-readable medium of claim 11, wherein the garment is a shirt or a cap.
