The present invention is described in detail below with reference to specific examples.
Example one
An embodiment of the present invention provides an ink output amount adjusting method, as shown in fig. 1, the method including:
s1, acquiring ink amount configuration parameters of each printing channel;
in the invention, in order to improve the data processing efficiency, in the process of storing the printing data, corresponding printing channels are configured for four standard colors CKMY to store the printing data of the standard colors. For example: configuring a first printing channel for storing printing data of a standard color C, and recording the first printing channel as a C-01 channel; configuring a second printing channel for storing the printing data of the standard color K, and recording the second printing channel as a K-02 channel; configuring a third printing channel for storing the printing data of the standard color M, and recording the third printing channel as an M-03 channel; a fourth print lane storing print data of a standard color Y is configured, denoted as the Y-04 lane.
The ink amount configuration parameters include: the adjustment channel, the selected channel and the ink amount adjustment mode of each selected channel of the current ink amount adjustment. The acquiring of the ink amount configuration parameters of each printing channel comprises:
s11, obtaining an adjusting channel and a selecting channel of the ink amount adjustment;
s12, acquiring ink amount adjusting modes of all selected channels;
the adjusting channel refers to a printing channel corresponding to a standard color of the current ink amount adjustment, and the selected channel refers to a printing channel corresponding to other standard colors selected by the current ink amount adjustment. The ink amount is sequentially divided into a first ink amount level, a second ink amount level ﹍, an Nth ink amount level, where N is a natural number, according to the size, and in the ink amount adjustment mode, the ink amount levels of the adjustment channel are respectively adjusted to the specified ink amount levels.
The ink volume levels can be classified into four levels, a large dot, a middle dot, a small dot, and no dot, according to the radius of the ink volume drop on the printing medium. One ink volume adjustment mode for the selected channel C-01 is: adjusting a large point to be a middle point, adjusting the middle point to be a small point, adjusting the small point to be a large point, and adjusting none to be a large point; another ink volume adjustment mode for the selected channel C-01 is: the large dot is adjusted to none, the middle dot is adjusted to a large dot, the small dot is adjusted to a middle dot, and none is adjusted to a small dot.
As shown in fig. 2, the ink amount adjustment of this time requires thickening the ink amount of the standard color C, specifically, the ink amount of the selected standard color K is adjusted from the first ink amount level to the second ink amount level, the ink amount of the standard color M is adjusted from the first ink amount level to the second ink amount level, and the ink amount of the standard color Y is adjusted from the second ink amount level to the third ink amount level; then, the adjustment channel of this ink amount adjustment is a C-01 channel, and the selected channel includes: k-02 channel, M-03 channel, and Y-04 channel. The ink amount adjustment mode of the K-02 channel is to adjust the large dot to be none, the middle dot to be the large dot, the small dot to be the middle dot, and none to be the small dot. The ink amount adjustment mode of the M-03 channel is such that the large dot is adjusted to none, the middle dot is adjusted to the large dot, the small dot is adjusted to the middle dot, and none is adjusted to the small dot. The ink amount adjustment mode of the Y-04 channel is to adjust the large dot to none, the middle dot to the large dot, the small dot to the middle dot, and none to the small dot.
S2, generating an ink quantity filtering template according to the ink quantity configuration parameters;
specifically, the step generates an ink amount filtering template according to the ink amount grade data of the selected channels and all the selected channels;
for example, 2bit represents four ink volume levels, where 00 represents a first ink volume level, 01 represents a second ink volume level, 10 represents a third ink volume level, and 11 represents a fourth ink volume level.
The ink amount filter template in units of 2 bits is then: [ M1M 2M 3 ].
Where Mi represents ink level data for the selected channel. As in FIG. 2, M1 represents ink level data for the selected channel K-02, including [00, 01, 10, 11 ]; m2 represents ink level data for the selected channel M-03, including [00, 01, 10, 11 ]; m3 represents ink level data for the selected channel Y-04, including [00, 01, 10, 11 ]; then FIG. 2 generates an ink volume filter template M in units of 2 bits as:
in addition, the invention can also generate the ink quantity filtering template by taking bytes as units, wherein 1 byte comprises 8 bits, namely comprises four pixels;

specifically, as shown in fig. 3, the present step includes:
s31, respectively acquiring the source data of the adjusting channel and the source data of the selected channel;
specifically, the method comprises the following steps:
s311, traversing all printing channels;
s312, judging whether each printing channel starts an ink quantity adjusting function or not;
s313, if the printing channel starts the ink amount adjusting function, the printing channel is an adjusting channel, and the source data of the printing channel is acquired as the adjusting channel data;
s314, traversing all selected channels of the adjusting channels, and acquiring source data corresponding to the selected channels as the source data of the selected channels.
S32, acquiring ink quantity filtering data of the selected channel in the ink quantity filtering template according to the ink quantity adjusting mode of the selected channel;

Wherein the ink amount adjustment mode of the K-02 channel is adjusted from a first ink amount level to a second ink amount level; the ink amount adjustment mode of the M-03 channel is adjusted from a first ink amount level to a second ink amount level; the ink amount adjustment mode of the Y-04 channel is adjusted from the second ink amount level to the third ink amount level. Take the example of a 2-bit ink volume filter template M, wherein,
as shown in fig. 2, when M1 is 01, the adjusted ink level representing the selected channel K-02 is the second ink level, M2 is 01, the adjusted ink level representing the selected channel M-03 is the second ink level, M3 is 10, and the adjusted ink level representing the selected channel Y-04 is the third ink level, the corresponding ink amount filtering data in the ink amount filtering template M in units of 2 bits according to the ink amount adjustment mode of the selected channel in fig. 2 is:
[01，01，10]。
s33, modifying the corresponding selected channel source data according to the ink filtering data to generate ink filtering intermediate data;
specifically, for a selected channel R, the ink amount filtering intermediate data R of the selected channel R can be obtained by replacing the data in the corresponding ink amount filtering data in the source data of the selected channel R with the ink amount filtering data corresponding to the selected channel, and the ink amount filtering intermediate data R of other selected channels can be obtained by replacing other selected channels with the same data. The ink amount filtering intermediate data of the selected channel constitutes the ink amount filtering intermediate data.
