The ink tank is a cylindrical container made primarily of clear plastic, while its top and bottom are covered in green caps. Player characters typically wear an ink tank on their back during battle as a way to store ink. As players use a weapon, the contents visibly decrease. When an ink tank is nearly out of ink, weapons can no longer be used in their regular state, and a notification appears, stating "low ink!". Ink tanks can be refilled slowly by ceasing to use a weapon, or quickly by being submerged in a puddle of similarly-colored ink. While submerged, an ink tank icon appears, displaying the current capacity of the ink tank that disappears once full. Using a special weapon immediately refills the ink tank.
The ink tank on the back of the player indicates the amount of ink in real time and flashes red when a player is out of ink. Upon using a weapon, the ink tank temporarily stops recharging ink, showing a white space where the ink was used until the player finishes. An LED on top of the ink tank lights up when there is enough ink to deploy the sub weapon and a small red arrow indicates how much ink is necessary to use it. While recharging ink, a slight sound effect occurs when enough ink has been restored to use the sub weapon.
Using the Inkling Squid amiibo gives the chance for the player to unlock limited-ink challenges for Gusher Gauntlet, Floating Sponge Garden, Inkvisible Avenues and Spongy Observatory in which the player has to complete the levels without running out of ink. Agent 3 is given additional ink tanks, represented by a large indicator that appears on the left side of the screen, showing how much ink is left. These extra ink tanks are in addition to the player's normal ink tank. Agent 3's Hero Shot initially uses up ink from the additional ink tank. However, submerging in ink only refills the regular ink tank. Once the additional ink tank is fully used up, Agent 3 can still use their regular ink tank, although it can no longer refill. Once the main ink tank is used up as well, the mission fails. The player is given one additional ink tank in Gusher Gauntlet, one and a half in Floating Sponge Garden and two in Inkvisible Avenues and Spongy Observatory.
In Splatoon 2, the ink tank functions identically to how it did it Splatoon, although it now has a more stylized design compared to the first game. The indicator to show how much ink is needed in order to use a sub weapon now appears in the icon while submerged in ink. In Version 3.2.0, a new version of the ink tank was introduced. It has 10% more ink capacity than the normal version, and is visually wider and has a rounded cap. It is exclusive to the Splattershot Jr. and its variants.

In the Octo Expansion, Agent 8 wakes up with a uniquely designed ink tank on their back, resembling more of a backpack than a bottle. It has a hook which is used to hold a balloon that fills up and explodes, splatting Agent 8 whenever they fail a test. Agent 8 still wears the ink tank even during unarmed missions. The Octo Expansion introduces the Ink Refill item, which instantly refills the tank to full when picked up, while also featuring the return of limited-ink challenges, comprising of Shrinky Ink Station, All That 8-Ball Station, Dinky Ink Station, and Ink & Watch Station. In this version of the challenge, the player receives no additional ink tanks but can use Ink Refill items. Submerging in ink does not refill the tank and displays a no symbol next to the indicator. Using up all ink leaves a couple of seconds to collect an Ink Refill. Failure to do so causes the mission to fail.

The ink tank in Splatoon 2.
The ink tank used in Octo Canyon.
A preview of the new ink tank used on the Splattershot Jr. and its variants.
- The ink tank resembles a sports bottle with a plastic cap on top. Splatoon 2 makes a closer resemblance with a curved indent in it and a plastic latch on top of the sub weapon light.
- The larger-capacity ink tank exclusive to the Splattershot Jr. and its variants has a baby bottle-like shape, referencing the fact that the Splattershot Jr. is the starting weapon for beginners.
- Due to the Splattershot Jr. having a 110% ink tank instead of the usual 100%, The Custom Splattershot Jr. can throw two Autobombs even without Ink Saver (Sub).
