Print Quality

Quality control in printing usually
begins with a printer’s standard
operating procedures (SOP). These
measures often ensure consistent
practices and color reproduction
throughout the facility.

Print quality refers to the quality of the hard copy or printout
produced by a printer.

Print Quality control the appearance of a print in terms of color,
registration, clarity, and the degree to which it resembles the
original.
Preparation

For many print runs, the first real step in the quality control process is
confirming the technical details of the print run with the client and
the print management company. The quote will cover the number,
size and expected completion date of any print run. Any mistake
here will prove costly later on.

Compatibility Files must be converted to the correct file type,
colours need to be in CMYK form and all images and typefaces
must be accessible to the print system.

Resolution and readability. The resolution of images is checked to
ensure that there will be no blurs or pixilation on the finished
product. Printers will also determine whether text will be readable
when printed.

Ordering, margins, bleeds. The layout and order of pages also
needs to be checked thoroughly before the print run properly
begins

Proof : For anything other than the smallest of print runs, a proof is
produced to give the client an accurate idea of what the final result
will look like. Digital proofs are commonly used to check text,
alignment and layout.

Machine maintenance and checks: Professional printers will carry
out routine maintenance on their printers, ensuring that the
machines are working efficiently at all times. Throughout each print
run, the results will be checked periodically to ensure that nothing
has gone awry. While today’s printers are far more reliable than the
machinery used in the past, this type of quality control is still
important.

Inspection and handover: The final products are usually inspected
by the supplier before they are handed over to the client, ensuring
that the client’s specifications have been met.
Printing Fault
