I purchased a second hand 2 color offset machine. The problem with the machine is though the condition of all the rollers is good there is an improper transfer of ink.
what is the reason for improper transfer of ink from ductor roller to the first inking roller of the ink train?
dear, first you check the impression setting between duct roller and first feed roller through 1 mm. thick film srtip.
now the question is how you will do this?
this setting is depend on type of the machine e.g. orient and manugraph. the general procedure is to set the impression that you adjust the cam or bolt both side of first inking roller.
second is check the first impression roller condition.

What is meant by the term offset printing?
It is an indirect printing method, hence the term offset. The image is first transferred from the metal plate to a rubber blanket, and then from there to the printing surface. It is one of the better printing methods and fairly cost effective.Offset printing was discovered by accident. They were using a rotary lithographic press and forgot to load it. When the operator loaded it next, he realized the resulting image was clearer when printed from the roller side.For smaller jobs, digital offset may be more cost effective, since you don't have the preparation costs, but it is a more expensive method for larger number of copies than standard offset printing. Rotogravure or photogravure gives slightly better quality than offset, but those are not cost effective until you get into hundreds of thousands of copies.
What are the advantages and disadvantages of offset lithography printing?
Consistent high image quality.Offset printing produces sharp and clean images and type more easily than letterpress printing because the rubber blanket conforms to the texture of the printing surface.Quick and easy production of printing plates.Longer printing plate life than on direct litho presses because there is no direct contact between the plate and the printing surface.Properly developed plates running in conjunction with optimized inks and fountain solution may exceed run lengths of a million impressions.Cost. Offset printing is the cheapest method to produce high quality printing in commercial printing quantities.Disadvantages of offset printing compared to other printing methods include:Slightly inferior image quality compared to rotogravure or photogravure printing.Propensity for anodized aluminum printing plates to become sensitive (due to chemical oxidation) and print in non-image/background areas when developed plates are not cared for properly.Time and cost associated with producing plates and printing press setup. This makes smaller quantity printing jobs impractical. As a result, smaller printing jobs are now moving to digital offset machines.
Is lithographic and offset printing the same?
yes, absolutely same... cuma offset lebih kepada proses pemindahan imej. manakala kaedah kerja cetakan tersebut dipanggil litografik (lithography)

What is a printing plate?
Printing processes such as offset printing use printing plates to transfer an image to paper or other substrates. The plates may be made of metal, plastic, rubber, paper, and other materials. The image is put on the printing plates using photomechanical, photochemical, or laser engraving processes. The image may be positive or negative. http://www.ezeeprinting.com/page/pulpboard-coasters

What is the cobb value for 70 gsm white printing paper for water damping web offset machine?
The Cobb value for 70 gsm white printing paper used in a water damping web offset machine is typically around 25-30 g/m2. This value indicates the paper's ability to absorb water and is important for maintaining print quality during the offset printing process.

Which printing process can be categorised as Digital Printing?
Generally when people talk about 'digital printing' it is in opposition of 'offset printing'. This can be confusing since they both begin with a digital source. Offset printing is the kind of printing that newspapers and magazines use where the print is separated into usually 4 different color plates (hence the word 'offset') whereas 'digital printing' relies on a digital file being sent to a RIP (it processes the file for the printer) then the RIP tells the printer how to squirt the ink onto the paper. No separations are needed for digital prints. The trend in printing is moving away from offset altogether, however offset's strengths have always been incredible speed (of printing) and cost effectiveness. As digital printing advances these differences diminish. HP even has a 'digital offset' printer that works like a modern digital printer, but with the capacity and speed to rival an offset printer.

What is offset positive plate?
An offset positive plate is a type of printing plate used in offset printing. It is sensitive to light, with the positive areas of the plate accepting ink and the non-image areas repelling ink. This allows for high-quality, detailed printing.
