Abstract
In some examples, continuous frequency based print pipeline generation may include ascertaining an input image that is to be printed. For a specified pixel of the input image, a first frequency and a second frequency that respectively correspond to first and second colors may be determined. Based on the first frequency and the second frequency, an intermediate frequency that is to be generated to produce an intermediate color relative to the first and second colors may be determined. The intermediate frequency may be converted to discrete pulses. Operation of a printhead that is to print the specified pixel may be controlled based on the discrete pulses.
Claims15
An apparatus comprising:
- a processor;
- and
- a non-transitory computer readable medium storing machine readable instructions that when executed by the processor cause the processor to:
- ascertain an input image that is to be printed;
- determine, for a specified pixel of the input image, a first frequency and a second frequency that respectively correspond to first and second colors;
- determine, based on the first frequency and the second frequency, an intermediate frequency that is to be generated to produce an intermediate color relative to the first and second colors;
- convert the intermediate frequency to discrete pulses;
- and
- control, based on the discrete pulses, operation of a printhead that is to print the specified pixel.
A computer implemented method comprising:
- ascertaining an input image that is to be printed;
- determining, for first and second specified pixels of the input image, a first frequency and a second frequency that respectively correspond to first and second colors;
- determining, based on the first frequency and the second frequency, an intermediate frequency that is to be generated to produce an intermediate color relative to the first and second colors;
- converting the intermediate frequency to discrete pulses;
- and
- controlling, based on the discrete pulses, operation of a printhead that is to print the first and second specified pixels.
A non-transitory computer readable medium having stored thereon machine readable instructions, the machine readable instructions, when executed, cause a processor to:
- ascertain an input image that is to be printed;
- determine, for a specified pixel or for first and second specified pixels of the input image, a first frequency and a second frequency that respectively correspond to first and second colors;
- determine, based on the first frequency and the second frequency, a plurality of intermediate frequencies that are to be generated to produce intermediate colors relative to the first and second colors;
- convert each of the intermediate frequencies to discrete pulses;
- and
- control, based on the discrete pulses for each of the intermediate frequencies, operation of a printhead that is to print the specified pixel, or the first and second specified pixels.
