Epson Artisan 835 - What are causing these microscopic line streaks?

[rajhlinux]

what type and brand of inks are you using - a dye ink for the Artisan 835 and pigment inks for the P600 ?

Yes, the Artisan 835 came with a CISS system, not sure if it is using dye.

The P600 is using original ink cartridges for the test prints I provided previously. However, I will use refillable cartridges and use UV blocking inks while utilizing only one ink channel. All other channels would be empty, and I am wondering if I should completely purge the printhead ink channels to be clean and empty until needed. I am not sure if the printer allows this and requires each print channel to physically contain liquid inks, as if it does pressure testing within each ink channel to confirm. If this is true, then I would now need to find a liquid that does not dry and is safe to stay in the ink channels for long-term storage until the ink channel is needed to be used.

I would expect that you get would get a similar improvement if you would use a pigment black on the Artisan printer for a test .

I'll order some pigment ink and test it out.
I'm not sure what some ways are that I can legitimately test whether the current ink I have is dye or pigment.

I don't think that you get such an improvement just because it is a P600, and what would be better with a P700 ? Using more inks would not make a difference for your B/W printing.

The improvement is not specifically towards inks; I bought the P600 specifically due to the improved hardware and software involved with the sophisticated printing machine. There is a great deal of precision engineering involved, such as the greater mass of the printer alone, which brings better print quality down to the micron realm.

Greater mass brings higher mechanical stability, fewer deflections, higher stiffness and less vibration.
If your printer is vibrating, rocking or shaking I'll guarantee it will not produce precision quality prints down to the micron space.

The most accurate machines in the world are extremely heavy to reduce mechanical uncertainties.
The precision machines used to make the Epson printheads are extremely heavy, weighing as much as a car. The precision motion cylindrical guide rails used to guide the print head along its Y-axis should also be of much higher quality than its predecessors. This, in turn, will produce a higher quality print. The higher value of the printer brings high-quality parts used inside the printer. The P600 is super heavy, which is good; Epson did this so that it can produce ultra-accurate prints down to the micron level (which it clearly does).

The P600 print head technology is also far superior to its predecessors. This thread alone shows that the P600 produces, so far, the best quality precision PCB trace prints. I've been researching this topic for two decades and haven't seen anyone produce as clean, sharp, and nearly perfect PCB prints as the ones I've provided from the P600, which were made by an inkjet printer.

With the few examples provided above, the P700/P900 must also provide at least 20% better precision print quality. Their linear cylindrical guide rails should also be slightly better than the P600, and the same goes for many of the various precision parts used inside the printer. It is not possible to obtain truly high-quality prints without using high-quality precision mechanical parts.

Not to mention, the Japanese also produces the world's most precise mechanical parts, aiding in making ultra-precise machines. Examples are mechanical components like precision linear guide rails, precision ball bearings, precision gears, precision ball screws, precision shafts, precision springs, precision bushings, precision motors, precision encoders, precision sensors, precision actuators, precision fasteners, precision belts and pulleys, precision couplings and the list goes on. (I'm sure several of these components are inside my Epson printer).

Also it is not a coincidence that the world's most best transparencies (at the consumer level) is also made in Japan, I'm sure you've heard about the "Pictorico Ultra premium OHP Transparency Film".

It might sound funny and hard to believe, but the Epson printer (specially the professional stuff) is indeed a classification of high-precision machine, a machine which precisely produces perfect prints as intended.
So, it would make sense that Epson's engineering department is economically sourcing high-quality precision parts locally, buying in bulk to make their products. They should use higher-quality parts for the more expensive products they advertise.

I'm not sure what some ways are that I can legitimately test whether the current ink I have is dye or pigment.

Look to the yellow ink in the reservoir tank for the 835 - dye inks are translucent - pigment inks are opaque - like milk - yellow milk in this case
