In particular, the Inky Impression is ideal for showing pop art, comic-book panels, and pixel art. We found that simpler images, without too much detail, tended to work best.
INKY BOX REVIEW DOWNLOAD
So it's far easier to download or transfer images to use straight away they just need to be 600×448 pixels, so may need scaling and/or cropping.
This means it can display standard RGB images without the hassle of having to alter the colour mode to a special indexed palette in an image editor, as is required on the Inky wHAT and pHAT.
INKY BOX REVIEW PLUS
In addition to its size, the other major plus point about the Inky Impression is that it now uses ACeP (Advanced Color ePaper) to deliver seven colours: black, white, red, green, blue, yellow, orange. The slimline board even features some breakout GPIO pins on the underside, including I2C and SPI, along with four tactile buttons on its left edge – these could be handy for switching between images or sets of them in a headless picture frame setup.
If using a Raspberry Pi 400, you’ll need a GPIO extender cable. Alternatively, it fits flush on a Raspberry Pi Zero without the extra header, for a reduced overall depth – great for putting it in a wooden frame for wall mounting. Care is needed to hold it by the edges when mounting, so as not to push down on the glass panel. Indeed, it's considerably larger than a full-size Raspberry Pi board, for which an extra female header (to boost height) and metal standoffs are supplied. Staining (hands): Washed off of my hands easily.Its 5.7-inch display is much bigger than Pimoroni’s previous e-ink boards, the Inky wHAT and pHAT.Staining (pen): Not seen after several days – easy clean-up.Nib Creep / “Crud”: Not seen, even after several days in the pen.Spread / Feathering / Woolly Line: Some seen.Show-Through: Some seen on the papers I used.Shading Potential: Plenty of shading and lovely green sheen.Vinta inks are available in attractive 30ml glass bottles from Cult Pens in the UK and Vanness Pen Store in the US. I found it quite difficult to read the handwritten script ink names on the paper labels. The paper label has an ink swab showing the colour and there is also one of these on the box. The English name is permanently printed in white on the bottle and the Filipino name is handwritten in script on a paper label further down the bottle. Sikatuna 1565 wrote quite wet and exhibited a fairly long dry time on my smooth papers.Īll of the inks I tested have two alternative names on their bottles, English and Filipino.
In my experience, this pen writes fairly wet. I tested these Vinta inks in my Pilot Custom 74 demonstrator pen with M nib.
It’s very easy to see the green sheen while writing. Sikatuna is a red ink with attractive shading on absorbent papers and heavy green sheen on smooth papers. This ink is Vinta Inks Sikatuna 1565 aka Sandugo from the sheening ink range. Vinta Inks are proudly made in the Philippines and for every bottle of ink sold the company makes a charitable donation towards the education of Filipino children, and to make their futures better.
